Someone who gets overly offended when heterosexuals refer to negative things as "gay".
Heterosexual #1: I can't believe we got homework over the break.
Heterosexual #2: I know, that's hella gay.
Homosexual: Pshh...I'm so offended by that statement *snaps fingers and wiggles hips*.
Heterosexual #s 1 & 2 in unison: Don't be such a Douchy McAntsatapicnic.
