Milk chugging contest

From USAFA Folklore

A Milk Chugging Contest typically occurs when MWR staff members arrange a morale building night. Essentially, several cadets gather in a circle around a trash can or trash bag and chug from gallon jugs of milk. The first to finish the jug, or the last to vomit, is the victor. It is an interesting sight to see several streams of milk shooting all at once from mouths to trashcans. It is even more interesting when the milk comes in a variety of flavors. Seeing white, pink, and brown shooting out of people is a revoltingly colorful specatacle. Sometimes you don't know whether to laugh or gag, but you just can't look away.

An AOC doesn't usual ban such events, and sometimes comes to watch, since they figure cadets could, as an unsafe alternative, be chugging beer somewhere, so this must in some way be better for them.
