polybuttock
The medical name given to a person who has more than one buttock (butt cheek). Usually people with this condition have two arsecracks and can fart in stereo.
Look at that freak, he has two arse cracks... I guess the poor guy is a polybuttock.
Did you hear that guy fart? That was polybuttock quality for sure!
