Party Jack 

When someone prepares a party well in advance with a group of friends and another 'friend' suddenly creates another party the day before the original party with the same group of friends thereby 'Party Jacking' the original party.

Jill sets a Christmas party on Dec 20th a month in advance for her group of friends, sends invites, hires a DJ, etc and then a week before, Emily decides to throw a Christmas party on Dec 19th with the same group of friends thereby 'Party Jacking' Jill's party. No Jill knows many of her friends will not show up to her party because they will be tired, hung over, not be able to get a baby sitter 2 nights in a row, etc, etc and is forced to cancel her party. Or if she does hold the party, it ends up being lame because few people show up due to already being partied out he night before.

party parts

Genitals, plain and simple. The parts that work for the sex including vagina, clitoris, and penis.

"When he looks at me, I get this feeling in my party parts."
"The other night I let him see my party parts."

Party Pooper 

Someone who ruins a party by not participating in something, or not making the party not fun in some way. Or doing stupid stuff to get attention and accidentally doing something bad and now everybody hates you even more.

Party Hat 

A fat joint in a cone shape, packed with weed. Its size and shape almost resemble that of a classic party hat and it is designed to deliver one hell of a party.

Party trick

The act by which your friend steals your stuff while you're not looking and puts them in his pants in a horrible manner and you can only sit and watch.

*John takes Barry's car keys while John talks to Joe*

Barry: "Hey John"
John: "What?"
*Barry holds up keys*
Barry: "Party trick"
John: "Oh god..."

*Barry pushes the keys up one leg of his pants, into the crotch area, and then reaches up the other leg, pulls them out, and hands them back to John*
