A drinking game invented at Princeton University involving exactly three people looking to get extremely drunk in a short span of time. Players compete in three consecutive rounds of chugging - the first with full beers. The next two rounds are initiated whenever the loser of the previous round of chugging decides to pull his next cup from the table. In both the second and final rounds, the loser of the previous round pulls a full beer while the other two players each pull a 2/3 beer. If one player loses all three rounds, he must immediately chug a full "penalty" beer, the instant he loses the final round.

The game receives its name because of the arrow formation of the cups. The first round of three is situated to form a triangle at the corner of a table, with one at the corner and the other two equidistant from it, on the two sides of the table that form the corner. The other two sets of beers (each set consisting of one full beer and two 2/3-full beers) are placed in a line going from the corner of the table to the center of the table. The penalty beer is placed at the center of the table. This formation creates the arrow pattern for which the game is named.

NB: Playing multiple games of Arrow in succession, including "best of 3" scenarios, is not recommended except for those with an extremely strong stomach.
