[2] A 2017 survey by the American Addiction Centers found flip cup to be the most quickly intoxicating drinking game played by those surveyed, with participants being able to reach a theoretical blood alcohol content of 0.08, the legal driving limit, within 20 minutes of play.

[3] Two teams of an equal number of players stand on opposite sides of a table, facing one another.

In front of each teammate is a disposable plastic cup filled with a set amount of beer.

At the start, it is customary for the initiating players to make a toast, after which the first member of each team drinks the entirety of their beverage.

Whichever team finishes drinking and flipping all its cups first wins.
