Roof Brooms 

A game played in an apartment consisting of hitting the ceiling with broom handles, usually played with six to ten players. The object of the game is to irritate the upstairs neighbor, often as revenge for noisy behavior such as stomping. Typically, roof brooms involves drinking beer, talking, and hammering on the ceiling for hours. Players may arrange themselves in shifts to ensure continual striking upon the ceiling.
