Seriously, though – YOU are closest… it is WALL BALL (two words):

“Wall Ball, also called Ball Wall, Patball, thumb, or Wallsies is a type of ball game involving a group which involves the bouncing of a ball against a wall, and throwing the ball or shoes at other players.

It is a popular school yard game, perhaps owing to the simplicity of equipment needed, namely a wall and a ball that bounces, (usually a tennis ball). It is likely that these games are distilled versions of fives, American handball, and other sports that date back to Greek and Roman times, such as expulsim ludere.”
