A game invented by the British Army in which is a lot like soccer. The differences are:

1. The goal is a post or a spot on the ground where the ball must be placed (not thrown), rather than an open goal

2. There are no rules. Anything goes except for the use of weapons and punching to the face or groin.

3. The winner is the team that accumulates the most points before the end of the game.

There are some variations such as 'last man standing murderball' and 'one point per hospitalisation'

Blue balls for the potential murderer. When you really want to kill someone, but you just can't for some reason. Weakness, not owning a gun, fear of the consequences, etc.
Johnny really wanted to pull a Virginia Tech at his college, but his dad had gotten rid of the family gun a few years back. Looks like he'd be stuck with murder balls.

(n.) A game seen in the movie SCUM (1979) which is very similar to basketball, except the winner is not the one with the most points, but the last team with people standing. The rules are


•NO punching in the face
•NO kicking in the goolies, and...
•NO biting


The teams divide up into 'black' and 'white'. Winning is only by default.
