A person who completely ruins a party by stopping the fun or completely ruining the mood. Basically an extreme version of the Party Pooper.

Someone who acts very pissed off and bitchy at a party, not wanting to drink, dance, or generally have fun. They will try to bring down the mood of the entire party with their debbie downer attitude. An extreme version of the party-pooper; most often girls who are pms-ing and/or who have hurt their shoulder.
Party-going friend: "Liz, you aren't a party pooper. You are a PARTY SHITTER"
Party shitter: "Guys, my shoulder hurts..."

Very similar to what is known as a "party pooper", but much worse. Someone who takes a massive hypothetical shit on the party, and completely ruins everyone's good time.
"The party was going so great, until Brian's girlfriend showed up. She completely shit on the entire party with her nagging and bitching."
"Damn man that sucks! She's such a Party Shitter!"
