noun: the victim of a pantsing. A pantsie is the guy you see at the mall or walking down the street wearing his pants low on the hips so you can see his skinny little ass, and also the fact that he wears bargain-basement boxers. You would create a pantsie by pulling down his pants. Usually a wannabe of some sort, as a pantsie must do something to show the world how great he wishes he were. BTW-why are pantsies only guys?
Imagine you're walking behind someone flashing his butt crack and his dirty shorts (change them once in a while, jag-off!) letting the world know he's secure in his surroundings, unafraid of being exposed for what he really is (an insecure loser). As a public service you decide to finish the job he started by lowering his pants to floor level, preferably while in the presence of the girl he really likes, or the kids who hate him. VOILA!! You have created a pantsie.
