In my
elementary school, it was called "
Butts Up." Because when people got to
throw the
ball at you, you put your hands on the wall and they pegged it at
your ass. Also, one
twist in our version, each time you got pegged, you got a letter, until you spelled out B-U-T-T-S-U-P. (Kinda like the basketball game
HORSE. When you had spelled it out, you had to go up to the wall one more time and let everyone peg you in the butt. We were
brutal!
Typically, the game was played with racquetballs (the small blue balls).
