The act of placing one's limp penis on the shoulder of an unsuspecting friend and saying "Polly wants a Cracker. another term for Mississippi Caterpillar. This can also be considered a clean way to do a Mississippi Mowhawk if the penis is placed up the unsucpecting person's head in the shape of a mohawk. I understand that Jimmy Buffet fans call this a Parrot Head gone wrong.
It was all fun and games until someone posted a video of Ryan Popping a Parrot on all the football players in the locker room before the game.
