-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.

Whilst this can be confused with the term 'Party Pooper', a slang term used to describe one who takes away the fun in a particular situation.

The 'Party-Pooper' is a prank that involves taking one's feces and placing it within an unused party popper. Once the party popper is pulled, the aforementioned feces is then shot out alongside the streamers.

Person 1: How was the party?

Person 2: It was pretty crappy once someone decided to pull a 'Party-Pooper'.
