ball
Many games include balls. Football, squareball, softball, tennisball. Here are some of the others. Murderball / Deathball : A pleasing mix of football, it, and violence. A football was kicked, and if it hit you without you controlling it and returning the ball, then you were chased and pulped.

Pissball : A new fluffy tennis ball is taken to the toilets and placed in the long piss filled gutter of the school urinal. Once nicely soaked it was hooked up with a deft foot and dribbled to the centre of the school yard. To commence the game, shout "PISS BALL" and boot the ball at the victim of your choice. This had three resulting outcomes. (1) A direct hit. The victim would smell like a trevor for the rest of the day, and a hundred boys would share the pride of having their piss on him. (2) The more sporty types with the quick reflexes may go for a catch. Pissy hand ensues.. (3) Miss. Needless to say a lot of kids stank of a lot of piss.

Domball : Not to be confused with DoomBall. Similar to Australian rules football, two (sloppily defined) teams of people would attempt to score by carrying, kicking or throwing Dominic to their end of the common room. Additional points were allegedly available for mid-play manoeuvres such as posting (qv). Games were started unpredictably with the rallying cry of "DOMBALL!" whenever Dominic was in the common room, which became decreasingly frequent as the game grew in popularity.
