To play defense when playing pool. This is done by knocking your balls in front of pockets, knocking the cue ball in a bad spot, or knocking an opponents balls in to bad spots. Ususally done when behind or when playing a superior player. See nigger pool
Should one player, play out an entire game and not pocket a single one of their own balls (excluding the white and/or eight ball) is concindered to have lost by seven balls. Thus resulting in that competitor having to drop their pants and make his way around the pub minus their own shorts.
7 Ball Loss (pub/taven pool rule)
If (1st player) doesnt sink a single one of their own ball and (2nd player) pots all their balls (including eight ball so long thus ball hasnt been sunk already)
(1st player) must make his way around pub and or taven without their pants
