Wow, this is better then my own game I made up called 'Frisball'. Despite what the title says, it contains no Frisbees or balls to speak of.
The rules are simple-
1: Former attire is mandatory (suit and tie, dress coat optional)
2: Two teams of unspecified sizes stand on either side of a football feild and throw bricks at each other.
3: The team who has the best parking wins.
