The word can be used as a n adjective and noun and I AM POSTING THE LINK HERE FOR YOU.The term "gay" can also be used as an adjective to describe things related to homosexuals or things which are part of the said culture. For example, while a gay bar is not itself homosexual, using the term "gay" as an adjective to describe the bar indicates that the bar is either homosexually-oriented, caters primarily to a homosexual clientèle, or is otherwise part of homosexual culture Using the term "gay" as an adjective where the meaning is akin to "related to homosexual people, culture, or homosexuality in general" is a widely accepted use of the word.

Although some dislike this usage, it is common particularly in the names of various organizations such as Parents, Families and Friends of Lesbians and Gays (PFLAG) and Children Of Lesbians And Gays Everywhere (COLAGE). It is sometimes used as a singular noun, as in "he is a gay", such as in its use to comic effect by the Little Britain character Dafydd Thomas. A 2006 BBC ruling by the Board of Governors has banned the pejorative use of the word. http://en.wikipedia.org/wiki/Gay
