For the novel by William S. Burroughs, see Queer (novel). For the song by Garbage, see Queer (Garbage song) The word queer has traditionally meant "strange" or "unusual," but its use in reference to LGBT (gay, lesbian, bisexual, transgender, intersex, asexual, etc.) communities as well as those perceived to be members of those communities has replaced the traditional definition and application. Its usage is considered controversial and underwent substantial changes over the course of the 20th century with some LGBT re-claiming the term as a means of self-empowerment. The term is still considered by some to be offensive and derisive, and by others as a re-appropriated term used to describe a sexual orientation and/or gender identity or gender expression that does not conform to heteronormative society.

in the nineteen-fifties, the term "queer" was a slur, a term of condemnation for people identified as homosexual.  Today, the term  usually represents stance towards homosexuality that does not fix it within a particular gender identity.  A "queer" is a person who, at least in theory, is willing to be lovers with either men or women.
