How to Play the popular college party game, flip cup
The College Forums.com explains how to play the drinking game Flip Cup. The guys demonstrate a one-on-one match, but the game is normally played using teams, with one team on one end of a table and the other team on the other end. Every player starts off with a cup full of beer. To start, two players, one from each team, tap their cups on the table, tap their cups together, tap it on the table, then down the whole beer. They then take their empty cups, put them on the side of the table, and flip it with a finger, trying to get it to land upside down. Whoever flips it successfully first, they win the round and their next teammate can go.
