tran-ade

A transvestite grenade. It is the moment when you realize, usually while extremely drunk and/or stoned, that the extremely hot chick you've been grinding all night on the dance floor is a transvestite.

The term was first coined on an episode of Jersey Shore when The Situation fell for one.

Dude is so smashed that he's missing all the clues that he's working a tran-ade!
