What is Ass Chugging?
1.
Drinking beer which is poured through the crack of another's ass on the way to the drinker's mouth. Usually a fraternity ritual where the drinker lies on his back, a bare-assed brother crouches directly over the mouth of the drinker, and another brother pours the beer down the length of the croucher's ass.
Surprisingly, the new low carbohydrate beers retain much of their crispness when they are ass chugged.
