Waterbuffalo

The word used in an ongoing drinking game in close-knit drinking circles when a poor fool has his beer/alcoholic beverage in his/her dominant hand.

When the word is yelled in an accusing way at this fool, they have to drink(or chug) whatever amount of alcohol is in the container of their dominant hand.
Not recommended for inexperienced drinkers.
Guy 1: "Dude, Steve got so trashed last night, he couldn't even see!"
Guy 2: "I know man, I waterbuffalo'd him four times in an hour!"

Dirty Waterbuffalo

When a person is not paying attention you walk up behind them and pee on the back of their leg.
