Someone that goes and poops at a party to make everyone avoid the bathroom and to put everyone in a bad mood because all they can smell in the entire house in the stinky poop.
-Dude this party sucks, it smells like poop all over your house so everyone just left or went outside.
-Yeah that was Craig who pooped in my bathroom downstairs.
-Yeah. Why would someone even poop downstairs? Is that sabotage? What a party-pooper.
