A woman who - unbeknownst to her at initiation of the relationship - has had two or more boyfriends break up with her resulting from coming out of the closet.
Marry - Hey Mark, so I hear your going out with Heather?
Mark - Yeah, its great - she's so nice and cute.
Marry - So... When are you going to come out of the closet?
Mark - WHAT!?!!?! Uhgghhh... What are you talking about?
Marry - You know Heather is a Gay Oven right? Her last 3 boyfriends broke up with her because they were gay.
