Answer 1

I think "Souds" wins ;););)

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."

Answer 2

Wallball.
