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!"
(high fives)

Albanian Water Buffalo 

When you have sex in the shower and she gets on the floor in the dark while wet and moans like a hippo while getting her ass plugged. Meanwhile her cousin comes in and collects the water dripping from her pussy and drinks it.

Chad: Yo how did that date go last night?
Mark: Great bro, I gave that girl an Albanian Water Buffalo. We even called her cousin for a more authentic experience.

National Lampoon Water Buffalo

The act of butt-chugging a beer, and then forcibly expelling it into a female’s vagina. As one fucks her sudsy, fecal snatch, one grabs the female by the ears and headbutts her unconscious.(Traditionally grunting added for special effect)

Tim asked Shauna if she remembered the National Lampoon Water Buffalo he had given the night before, but her concussed ass had no recollection.
