Pomosexual (short for Post-Modern) is a term popularized by sex-positive activists and writers Carol Queen and Lawrence Shimel in their 1997 Anthology "Pomosexuals: Challenging Assumptions about Gender and Sexuality." People identified as pomosexuals are attempting to redefine, reassess, and protest current essentialist-bound labels surrounding sexual orientation.
In online slang, it also refers to people who claim to be bisexual because they think it's hip but would not have a sexual encounter with someone of the same sex. You may see this term in the chat rooms or newsgroups.
