A highly complicated and potentially dangerous dance move that involves getting in push up position, performing two 'humps' and then pushing yourself up off the ground, only to land in the same position and repeat the cycle.
Move back, clear the floor! My boy's gonna do the hump-hump jump.
The unattractive, and usually fat, slutty girl at every party. Hump Whales usually think that they're hot, but they really aren't. They are just used as back-up hookups when guys can not get a hot girl at a party. Hump Whales are quick to get drunk (usually faking), loud and obnoxious, and will flirt with and hook up with any guy they see.
Guy #1: Why are so many guys all over that girl? It's not like she's attractive.
Guy #2: Dude, there's like a 1:4 girl to guy ratio at this party. She's the Hump Whale. It's her time to shine.
