A drinking game in which a 25 cup diamond (5 cups wide) is placed in the middle of a table. Teams of up to three compete using three ping pong balls to eliminate the opposing teams territory by shooting the balls into the 10 cup triangle opposite the middle five cups, called borderline. The row called borderline are the only five cups not filled with beer, they are filled normally with water or soda. When you make a borderline cup, you have the option to either take an additional shot, or add that cup to your territory causing the other team to have another cup to make.
Alyssa and Kate never lose at territory.
