Very similar to a gold digger, but with one key difference. A party digger uses men to get to parties. This manipulation may include making men having parties, making the man drive them to a party, or drinking another man's alcohol. Men can be party diggers too, but it is usually to a lesser extent.
Zach: Damn man, That girl Tammy is a mad party digger.
Joel: I know, just last week she sucked my dick for a ride out to Jake's party. And she drank all my liquor.
Kanye: True dat dogs, but I aint saying she a party digger, but she ain't fucking with no loser niggers.
