Flipcup is great! It's a drinking game where you have 2 or more teams, in a line, in front of a table. Each person has a cup of beer. The first people of each of the teams have to drain their cups, put them on the table and try to flip them over so that they land upside down; the next person in line can't drink until the first person gets their cup to land right. It keeps going like that until one team finishes first, and they win.
