Original name for a party which takes place overnight, and all the gamers stay up all night playing video games. (note, the game system does not have to be a gamecube)
Dude, at my 24 hour gamecubeathon, only Alex, Anthony and I managed to stay awake. Andy, Sam, and Tanner fell asleep... while Cullen didn't even make it.
