Party Pooper 

Before ejaculating on your partners face, shove a handful of confetti in your anus. After ejaculating quickly turn around and fart out the confetti on your partners face causing it to adhere to the semen. Often followed up by the male yelling "Surprise!"

I had leftover confetti in my house so what else would I do? I gave her a party pooper of course.

Party Pooper Steve 

Normally a pretty cool guy, usually very good looking - and then he goes on vacation and although he had a great time he decides to put a price tag on fun and memories.

Alison, "I had a blast in Vegas, did you Lindsey?"
Lindsey, "Yes I had a good time, until Party Pooper Steve flipped his shit because we spent some hard earned money!"

Ass that you invite to the party that eventually starts being stubborn and ruins the fun.

It would be funny to stick a party pooper's head in the punch bowl

party-pooper 

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.
