According to Wikipedia:
Flip cup is a team-based drinking game. Effectively a drinking relay race, it is the North American equivalent of boat race. Alternate Names include Tip Cup, Flippy Cup, Tippy Cup and Canoe, which was the original name for the game as developed in bars and parties the South Side of Chicago, named as such because of the way a canoe tips with people rocking back and forth. The two teams stand on both sides of a table, facing one another (the person in front of a player is his/her opponent). In front of each teammate is a cup filled with an arbitrary amount of any kind of liquid (often beer). A player and his opponent both have the same amount of liquid. At the start of the race, the first member of each team drinks his or her beverage. When finished, the cup is placed right-side up at the edge of the table, and the person who drank it tries to flip it upside down onto the table. If he or she is not successful on the first try, the cup must be reset and re-flipped. Only after the first teammate is done flipping the cup successfully, can the next person proceed. Whichever team finishes drinking and flipping all its cups first is the winner.
Last night after kickball (when my team the Pickled Yaksman were defeated in the first round of playoffs) we headed to the bar to have a few drinks! Well, immediately a flip cup tournament ensued. It's just amazing to me how quickly you can get caught up in the game!
Good times were had all around!!!
