Question: The title of the Ghosts film is a reference to what Cantonese slang term that is used in Cantonese to refer to Westerners, and applies to European ethnicities in its unmodified form.

Context paragraphs:
Beard (companion): Beard is a slang term describing a person who is used, knowingly or unknowingly, as a date, romantic partner (boyfriend or girlfriend), or spouse either to conceal infidelity or to conceal one's sexual orientation.  The American slang term originally referred to anyone who acted on behalf of another, in any transaction, to conceal a person's true identity.  The term can be used in heterosexual and homosexual contexts, but is especially used within LGBT culture.  References to beards are seen in mainstream television and films, and other entertainment.

Lingnan culture: Lingnan culture (Cantonese Jyutping: Ling naam man faa; Traditional Chinese characters: 嶺南文化) refers to the culture of the core Lingnan region - the provinces of Guangdong ("Gwongdung" in Cantonese) and Guangxi ("Gwongsai" in Cantonese) in southern China.  In a purely geographical sense, this term can include Hakka culture and Teochew culture in the area.  The term is, however, more typically used to refer to Cantonese culture, which has historically been the dominant cultural force in Gwongdung and the eastern half of Gwongsai.  Here, this term also includes culture of Hong Kong and culture of Macau, since the people of Hong Kong and Macau are largely Cantonese.  Lingnan culture is the subject of research at several institutions such as the Centre of Lingnan Culture studies.  It is often contrasted against the culture of China's northern plains (i.e., Zhongyuan culture).

Zips: Zips (also Siggies or Geeps) is a slang term often used as a derogatory slur by Italian American and Sicilian American mobsters in reference to newer immigrant Sicilian and Italian mafiosi.  The name is said to have originated from mobsters' inability to understand the faster-speaking Sicilian dialects, which appeared to "zip" by.  Other theories include pejorative uses such as Sicilians' preference for silent, homemade zip guns.  According to still another theory, the term is a contraction of the Sicilian slang term for "hicks" or "primitives."  The older Sicilian mafiosi of pre-Prohibition known as "Mustache Petes" (who eventually were deposed by American-born mobsters during the Castellammarese War) were also referred to as zips.

List of European cuisines: This is a list of European cuisines.  A cuisine is a characteristic style of cooking practices and traditions, often associated with a specific culture.  European cuisine (also called "Western cuisine") refers collectively to the cuisines of Europe and other Western countries.  European cuisine includes cuisines of Europe, including (depending on the definition) that of Russia, as well as non-indigenous cuisines of North America, Australasia, Oceania, and Latin America, which derive substantial influence from European settlers in those regions.  The term is used by East Asians to contrast with Asian styles of cooking.  This is analogous to Westerners referring collectively to the cuisines of Asian countries as Asian cuisine.  When used by Westerners, the term may refer more specifically to cuisine "in" Europe; in this context, a synonym is Continental cuisine, especially in British English.

Cantonese slang: Cantonese slang is a type of slang used in areas where Cantonese language is spoken.

European cuisine: European cuisine, or alternatively Western cuisine, is a generalised term collectively referring to the cuisines of Europe and other Western countries, including (depending on the definition) that of Russia, as well as non-indigenous cuisines of Australasia, the Americas, Southern Africa, and Oceania, which derive substantial influence from European settlers in those regions.  The term is used by East Asians to contrast with Asian styles of cooking.  (This is analogous to Westerners' referring collectively to the cuisines of East Asian countries as Asian cuisine.)  When used by Westerners, the term may sometimes refer more specifically to cuisine "in" Europe; in this context, a synonym is Continental cuisine, especially in British English.

Ars (slang): Ars (Hebrew: ערס‎ ‎ "`ars "), or Arsim (the plural in Hebrew) is a derogatory Hebrew slang term for the Israeli stereotype of a low-class young man.  The stereotype may also refer to personal effects such as flashy jewelry and clothing.  A woman fitting this stereotype is an "Arsit" (though this usually implies masculinity in the woman), the word formed by adding the Hebrew feminine ending "it" to the Arabic word "Ars" (Arabic: عرص‎ ‎ , "ʿarṣ ").  Another term used for women is "Freḥa" (פרחה), originally a female Moroccan first name popular in the 1950s and the 1960s, during the large immigration wave from Morocco to Israel.  The Ars subculture traditionally was associated with young Jews of Middle Eastern origin, but in recent years has expanded to a broader range of ethnicities.  In particular, the term "Freḥa" is nowadays used in reference to intellectually shallow girls of all ethnicities, like bimbo or airhead in English.

Ghosts (2006 film): Ghosts is a 2006 drama film directed by Nick Broomfield, based on the 2004 Morecambe Bay cockling disaster.  The title is a reference to the Cantonese slang term "Gweilo" (鬼佬), meaning "ghost man", used for white people.

Dongo: Dongo may refer to: The mix between a dingo and any other dog is referred to as a "Dongo" and also is a slang term for male genitalia.  Dongo is also reported to be, but is not widely used, as a slang term in Australia as a substitute for the color orange.

Gweilo: Gweilo or gwailou (, pronounced ] ) is a common Cantonese slang term for Westerners.  In its unmodified form, it applies only to European ethnicities and has a history of racially deprecatory use.  Cantonese speakers frequently use "gwailou" to refer to Westerners in general use, in a non-derogatory context, although whether this type of usage is offensive is disputed by both Cantonese and Westerners alike.
