LGBT slang
LGBT slang, LGBT speak, or gay slang is a set of slang lexicon used predominantly among LGBT people. It has been used in various languages since the early 20th century as a means by which members of the LGBT community identify themselves and speak in code with brevity and speed to others. History and context. Because of sodomy laws and threat of prosecution due to the criminalization of homosexuality, LGBT slang has served as an argot or cant, a secret language and a way for the LGBT community to communicate with each other publicly without revealing their  sexual orientation to others. Since the advent of queer studies in universities, LGBT slang and argot has become a subject of academic research among linguistic anthropology scholars. During the first seven decades of the 20th century, a specific form of Polari was developed by gay men and lesbians in urban centres of the United Kingdom within established LGBT communities. Although there are differences, contemporary British gay slang has adopted many Polari words. The 1964 legislative report "Homosexuality and Citizenship in Florida" contains an extensive appendix documenting and defining the homosexual slang in the United States at that time. SCRUFF launched  a gay-slang dictionary app in 2014, which includes commonly used slang in the United States from the gay community. Specialized dictionaries that record LGBT slang have been found to revolve heavily around sexual matters. Slang is ephemeral. Terms used in one generation may pass out of usage in another. For example, in the 1960s and 1970s, the terms "cottage" (chiefly British) and "tearoom" (chiefly American) were used to denote public toilets used for sex. By 1999, this terminology had fallen out of use to the point of being greatly unrecognizable by members of the LGBT community at large. Many  terms that originated as gay slang have become part of the popular lexicon. For example, the word "drag" was popularized by Hubert Selby Jr. in his book "Last Exit to Brooklyn". "Drag" has been traced back by the Oxford English Dictionary (OED) to the late 19th Century. Conversely, words such as "banjee", while well-established in a subset of gay society, have never made the transition to popular use. Conversations between gay men have been found to use more slang and fewer commonly known terms about sexual behavior than conversations between straight men. In the Philippines, many LGBT people speak  with Swardspeak, or "gay lingo", which is a more extensive use of slang as a form of dialect or way of speaking. Other argots are spoken in southern Africa (Gayle language and IsiNgqumo) and Indonesia (Bahasa Binan).
