look up any word, like bootylicious:
1. Unanimous Party Pact
Also know as UPP, A unanimous agreement within everybody at one party to convince one or two drunken idiots to do something incredibly stupid. Usually consisting of a fight or an unforgettable party prank.
1: Orin: "Hey Eric, that Chad that's dancing by himself over there just told me he donkey punched your mom last night!"
Eric (already wasted): "That son of a bitch! I'm gonna go rip his heart out and stick it in the microwave!"
Hours later:
Officer Malone: "What do you think happened here?"
Officer Holsclaw: "Well Malone, this looks like a clear cut case of a Unanimous Party Pact, because everyone seems to find it funny, and nobody's spilling any details."
Officer Malone: "Well, lets get this body out of here"

2: Eric (to Sonny): "Hey man, Derick just told me that he donkey punched your sister earlier today"
Orin (to Derick): "Dude Derick, Sonny just told me he donkey punched your sister 20 minutes ago!"
Thus commences an epic fight of drunken proportions.

3: Eric and Orin (to Andy): "Hey dude, I bet you can't donkey punch that booze wench by the end of the night"
Andy: "Is that Molly? I'll take that bet!"
2. Mexican roulette
At a party or any other social function:

-Buy a box of condoms
-Take out one condom
-Take a pin and puncture the condom while in the wrapper
-Put the punctured condom back into the box
-Let people take the condoms freely

Much like russian roulette, this will end up with your life ending.
Person 1: "Did you hear Josh Chavez's cousins' friend got pregnant"?

Person 2: "Yeah, she was at a party a few weeks ago, we played mexican roulette".

Person 1: "You're going to hell".

Person 2: "I know".
3. Closet Monster
This is where you hide alot of your friends in a room where you know you will have sex, normally done at a party or gala event.

You take a girl (or rarely, a boy) whom you have no respect for into the room and commence having sex with her/him.

Right at the moment of climax, you give the prearranged signal and all of your friends emmerge laughing to scare and severly embarrass the victim
Dude, did you hear about Ellen?

No what happened?

At that party last weekend Cole Closet Monstered her! Matt, Jordan, and Evan were all hiding in the room
4. Party Roll
Attempting to get the song "Party in the USA" by Miley Cyrus stuck in someones head for the purpose of driving them insane. This can be done either by playing the song, linking to a YouTube video of the song, or quoting the lyrics.
That stupid "Party In The USA" song has been stuck in my head since you party rolled me last week.
5. Schenk Prank
When engaging in intercourse with a man/women, pull out, spit on their back and when they turn around blow your load right in their face. then punch her in the throat and say "This Is A Lovely Tea Party"
"Holy Shit, I know that guy just didn't do a schenk prank to Brett"

6. soft batch
A foul party prank in which one turns on someone's oven (to preheat it) then sneaks a cookie sheet into the bathroom. A tasty dump is then taken on the cookie sheet and when the coast is clear the sheet is placed in the already warm oven. The culprit then usually leaves the gathering as it only takes about five minutes for the entire place to reek of dung. A horrible mess to clean up as well.
"You go to Mary's party last night?"
"Yeah, it sucked. I left her a nice soft batch though."

7. top shelf
When one takes a crap in the water tank of a toilet. This is usually done as a party prank or as a method of smiting one's enemies. It's a real pain to clean out, stinks like hell, and makes the toilet flush brown for days.
That guy wouldn't give me a beer at the party at his house last night, so I gave him a top shelf.
