Flirting
Flirting or coquetry is a social and sexual behavior involving spoken or written communication, as well as body language, by one person to another, either to suggest interest in a deeper relationship with the other person, or if done playfully, for amusement. Flirting usually involves speaking and behaving in a way that suggests a mildly greater intimacy than the actual relationship between the parties would justify, though within the rules of social etiquette, which generally disapproves of a direct expression of sexual interest in the given setting. This may be accomplished by communicating a sense of playfulness or irony . Double entendres (where one meaning is more formally appropriate, and another more suggestive) may be used. Body language can include flicking the hair, eye contact, brief touching, open stances, proximity, and other gestures. Flirting may be done in an under-exaggerated, shy or frivolous style. Vocal communication of interest can include, for example, Flirting behavior varies across cultures due to different modes of social etiquette, such as how closely people should stand (proxemics), how long to hold eye contact, how much touching is appropriate and so forth. Nonetheless, some behaviors may be more universal. For example, ethologist Irenäus Eibl-Eibesfeldt  found that in places as different as Africa and North America, women exhibit similar flirting behavior, such as a prolonged stare followed by a nonchalant break of gaze along with a little smile. Etymology. The origin of the word "flirt" is obscure. The "Oxford English Dictionary" (first edition) associates it with such onomatopoeic words as "flit" and "flick", emphasizing a lack of seriousness; on the other hand, it has been attributed to the old French "conter fleurette", which means "to (try to) seduce" by the dropping of flower petals, that is, "to speak sweet nothings". While old-fashioned, this expression  is still used in French, often mockingly, but the English gallicism "to flirt" has made its way and has now become an anglicism. The word "fleurette" was used in the 16th century in some sonnets, and some other texts. The French word "fleurette" (small flower), and the language of old south France word "flouretas" (from the Latin "flora" (for flower)), are related to some little says where flowers are both at the same time a pretext and the comparison terms. In southern France, some usage were yet used in 1484, In French, some other words more or less related are  derived from the word fleur: for instance "effleurer" (English: lightly touch) from 13th century "esflourée"; "déflorer" (English: deflower) from 13th century "desflorer" or (fleuret (English Foil) 18th century. The association of flowers, spring, youth, and women is not modern and were yet considered in ancient culture, such as the Chloris in ancient Greece, or Flora (deity) in the ancient Roman Empire, including Floralia festival, and in other older poems, such as the Song of Songs. History. During World War II, anthropologist Margaret Mead was working in Britain for the British Ministry of Information and later for the U.S. Office of  War Information, delivering speeches and writing articles to help the American soldiers better understand the British civilians, and vice versa. She observed in the flirtations between the American soldiers and British women a pattern of misunderstandings regarding who is supposed to take which initiative. She wrote of the Americans, "The boy learns to make advances and rely upon the girl to repulse them whenever they are inappropriate to the state of feeling between the pair", as contrasted to the British, where "the girl is reared to depend upon a slight barrier of chilliness... which the boys learn to respect, and  for the rest to rely upon the men to approach or advance, as warranted by the situation." This resulted, for example, in British women interpreting an American soldier's gregariousness as something more intimate or serious than he had intended. Communications theorist Paul Watzlawick used this situation, where "both American soldiers and British girls accused one another of being sexually brash", as an example of differences in "punctuation" in interpersonal communications. He wrote that courtship in both cultures used approximately 30 steps from "first eye contact to the ultimate consummation", but that the sequence of the steps was different. For  example, kissing might be an early step in the American pattern but a relatively intimate act in the English pattern. Japanese courtesans had another form of flirting, emphasizing non-verbal relationships by hiding the lips and showing the eyes, as depicted in much Shunga art, the most popular print media at the time, until the late 19th century. European hand fans. The fan was extensively used as a means of communication and therefore a way of flirting from the 16th century onwards in some European societies, especially England and Spain. A whole sign language was developed with the use of  the fan, and even etiquette books and magazines were published. Charles Francis Badini created the Original Fanology or Ladies' Conversation Fan which was published by William Cock in London in 1797. The use of the fan was not limited to women, as men also carried fans and learned how to convey messages with them. For instance, placing the fan near the heart meant "I love you", while opening a fan wide meant "Wait for me". In Spain, where the use of fans (called "abanicos") is still very popular today, ladies used them to communicate with suitors or prospective suitors without  attracting the notice of their families or chaperons. This use was highly popular during the 19th and early 20th centuries. Purpose. People flirt for a variety of reasons. According to social anthropologist Kate Fox, there are two main types of flirting: flirting just for fun and flirting with further intent. In a 2014 review, Henningsen made a further distinction and identified six main motivations for flirting: sex, relational development, exploration, fun, self-esteem and instrumental. Henningsen found that often, many flirting interactions involve more than one of these motives. There also appears to be gender differences in flirting motivations. Courtship . Many people flirt as a courtship initiation method, with the aim of engaging in a sexual relationship with another person. In this sense, flirting plays a role in the mate-selection process. The person flirting will send out signals of sexual availability to another, and expects to see the interest returned in order to continue flirting. Flirting can involve non-verbal signs, such as an exchange of glances, hand-touching, and hair-touching; or verbal signs, such as chatting, giving flattering comments, and exchanging telephone numbers in order to initiate further contact. Many studies have confirmed that sex is a  driving motivation for flirting behaviours. Additionally, Messman and colleagues' study provided support for this hypothesis; it demonstrated that, the more one was physically attracted to a person, the higher the chances one would flirt with them. Flirting with the goal of signalling interest appears as a puzzling phenomenon when considering that flirting is often performed very subtly. In fact, evidence shows that people are often mistaken in how they interpret flirting behaviours. Thus, if a main purpose of flirting is to signal interest to the other person, why isn't this signalling done more clearly and explicitly?A possible explanation for  the ambiguous nature of human flirting lies in the costs associated with courtship signals. Indeed, according to Gersick and colleagues, signalling interest can be costly as it can lead to the disturbance of the nature of a relationship. For instance, signalling sexual interest to a friend bears the risk of introducing uncertainty into the friendship, especially if the romantic advance is rejected by the recipient. For this reason, individuals prefer engaging in a flirting interaction that is more subtle to limit the risks associated with the expression of sexual interest. More generally, human relationships are governed by social norms and  whenever these are broken, one can suffer significant costs that can range from social, economic and even legal nature. As an illustration, a manager flirting with his subordinate can lead to strong costs such as being accused of sexual harassment, which can potentially lead to job loss. Additionally, third parties can impose costs on someone expressing sexual interest. Expressing sexual interest to somebody else's romantic partner is a highly punishable act. This often leads to jealousy from the person's partner which can trigger anger and (possible) physical punishment, especially in men. Third parties can also impose costs through  the act of eavesdropping. These can lead to damage to one's reputation leading to possible social, economic and legal costs. A last point to consider is that the costs associated with interest signalling are magnified in the case of humans, when compared to the animal world. Indeed, the existence of language means that information can circulate much faster. For instance, in the case of eavesdropping, the information overhead by the eavesdropper can be spread to very large social networks, thereby magnifying the social costs. Other motivations. Another reason people engage in flirting is to consolidate or maintain a romantic  relationship with their partner. They will engage in flirting behaviours to promote the flourishing of their relationship with their partner. People will also flirt with the goal of 'exploring'. In this sense, the aim is not necessarily to express sexual or romantic interest but simply to assess whether the other might be interested in them before making any decision about what they would want from that individual. Henningsen and Fox also demonstrated that flirting can sometimes be employed just for fun. For instance, studies have shown that flirting in the workplace was used mostly for fun purposes. Another motive that  drives flirting is developing one's own self esteem. People often feel highly valued when someone flirts with them. Therefore, often people flirt to encourage reciprocation and thereby increase their self esteem. As a last point, people might flirt for instrumental purposes. For instance, they will flirt to get something out of the other person such as a drink in a nightclub or a promotion at work. Gender differences in motivations. Certain types of flirting seem to be more common amongst males compared to females and vice versa. To start with, Henningsen and colleagues' study demonstrated that flirting with sexual  intent was found to be more prominent amongst men. On the other hand, flirting for relationship development purposes was more often employed by women. These findings are not surprising when the parental investment theory is taken into account. First, it states that females are more choosy and men more competitive, therefore predicting that flirting as courtship initiation will be more commonly used amongst men. The theory also predicts that females invest more in their offspring, which makes them more prone to invest in their relationship as this can provide resources that can contribute to their offspring's survival. On the  other hand, men have no guarantee that their mates' offspring is theirs, so have fewer incentives to seek long-term relationships; thereby explaining why men care less about flirting for relationship development. Additionally, Henningsen found that flirting for fun was more common in females than males. A possible explanation for this could lie in the fact that women engage in what he calls "practice flirting". As women are more selective and want to attract the best partner to take care of their offspring, they might flirt for fun to practice and evaluate what flirting behaviours work the best. Examples. Flirting  may consist of stylized gestures, language, body language, postures, and physiologic signs which act as cues to another person. Among these, at least in Western society, are: The effectiveness of many of these interactions has been subjected to detailed analysis by behavioral psychologists, and advice on their use is available from dating coaches. Cultural variations. Flirting varies a great deal from culture to culture. For example, for many Western cultures one very common flirting strategy includes eye contact. However, eye contact can have a very different meaning in some Asian countries, where women might get in trouble if they return  a glance to men who stare at them. Furthermore, Chinese and Japanese women are sometimes not expected to initiate eye contact as it could be considered rude and disrespectful. The distance between two people is also important when flirting. People from the "contact cultures", such as those in the Mediterranean or Latin America, may feel comfortable with closer proximity, whereas a British or Northern European person may typically need more space. Although touching, especially of the hand or arm, can constitute flirting, touching is also often done without intentions of flirting, particularly in the contact cultures where it forms a  natural part of communication. In Japan, flirting in the street or public places is known as "nanpa".
