Dome Cappin' 

An activity in which one person throws a flat billed hat onto the head of another person. It doesn't stop at the basics, however. It can be expanded by using stairs, wind, different styles of throwing and any and all of your own personal variations of the game.

Throwing a Rangers flat bill onto the head of your friend who's downstairs is an excellent way to begin your Dome Cappin' career.
