Butts Up is played with a ball (such as a tennis ball) on a paved surface against a wall.

The object of the game is to be the last player remaining in the game after all other players are out.

Rules:

1) The first player starts the game by throwing the tennis ball against the wall with having the ball hit the wall without hitting the ground first.

2) After the ball makes contact with the wall and bounces off the ground at least once, any of the players may then try to catch the ball. If catcher mishandles the ball and the ball touches the ground, the catcher must try to touch the wall before another player fields and throws the ball against the wall. If the ball touches the wall before the catcher, the catcher is out and must face various consequences.

3) If the ball is caught before hitting the pavement, the thrower is penalized with one “out”. After three outs a player leaves the game.

4) If the thrower’s ball bounces before hitting the wall, the thrower must run to the wall and touch the wall before an opponent can pick up the ball and throw it to the wall.

5) If the original thrower doesn’t make contact with the wall before the ball reaches the wall, the original thrower is out.

6) If the thrower reaches for the ball, but has it bounce off his fingers and onto the pavement, this counts as missing the throw, and he must run to the wall.

When a person is sick and when they go to use the bathroom to take a dump, a sudden urge of vomiting arise and with no to wipe, flush, and pull your pants up, they get on their knees and vomit with their naked butt up in the air.
My mom caught me in the bathroom with butt-up syndrome. She asked me "Saba why do you have your pants down when you are vomiting" I replied, "Because I didn't have time to wipe and pull them up!"
