This is a variation on the game of American football, the game has the same rules as far as scoring but the little yellow flag does not exist, the ball is played by either a chunk of wood or rock or anything large and heavy. In this game you may bash,hit,strike,assault,smack,kick the shit out of, or any combination of the above with or without the ball. This game is a common Thanksgiving day activity in the redneck states.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.

A variation of dodgeball played with two mats, one on each side of the court, gym, etc. When players get out, they go to the mat (or prison) on the other side of the court. To get back in the game, they must catch a ball thrown from a teammate on the other side. The game continues until an entire team is in prison, making the opposing team the winner.

Prison ball means not have busted a nut in a long while causing the balls of a male to become sore. The feeling is similar to getting kicked in the nuts.

After Loosing a game, a person that looses usually says "Prison Rules, pussy" and then starts to get physical because they lack the skills. But the winner usually ends up winning again anyway
