The game that the hot twins in "Harold and Kumar go to White Castle" play in the bathroom. The game consists of diarrheaing by one person then the other person trying to match it or beat it in noise, stink, or both.
Tiffany: (in the bathroom stall) Hey Beth wanna play a game of Battle Shit?

Beth: Sure!

Tiffany: Diarrhea*

Beth: Louder Diarrhea*

Tiffany: Extreamly Loud and Stinky Diarrhea*

Beth: Tiffany you sank my Battle Ship
