A game where you throw a tennis ball so that it bounces and then hits the wall, then the next player has to do the same.
The ball is allowed to bounce once after it hits the wall, failure to hit the ball results in the player who missed it to go out. Boundries exist, height and width.
When the ball hits exactly between the floor and the wall it is called 'Mids' and a rethrow is taken.
When someone gets in the way of you hitting the ball 'Obbs' is called and a rethrow takes place.
The one who serves the ball, is allowed one fault/bad serve.
This game was created in 1999 by KFX of Gunnersbury Catholic School when Gibbon banned hard footballs in the playground and allowed only sponge balls -costing 5 pounds - though worth less than 20p. Patball grew in popularity until it was banned in 2000, though this ban was ignored by the pupils, and even today with the original creators having left the school the sport is still thriving.
The definition of patball is pretty self explanatory.
Though in latter years a bouncy ball instead of a tennis ball was sometimes used.
