Game where a group of friends throws a ball on a wall. If you accidentally drop the bal trying to catch it, you have to run to the wall and tag it as fast as you can before someone else throws the ball. If the ball hits the wall before you tag it you are out of the game. If you get 3 outs you have to stand up against the wall and have the person who gave you the last out stand as far as possible and try to throw the ball at you.

The coolest, most extreme sport ever and the only name for the game.
