An adjective used by some people, particularly younger people, whose sexual orientation is not exclusively heterosexual (e.g., queer person, queer woman). Typically, for those who identify as queer, the terms lesbian, gay, and bisexual are perceived to be too limiting. Once considered a pejorative term, queer has been reclaimed by some LGBT people to describe themselves; however, it is not a universally accepted term even within the LGBT community.
The term should only be used for people or organizations that use queer to identify themselves. Do not use it when intended as a slur.
