Pubic Hand 

1. The act of rubbing your unwashed crotch and then shoving your hand in someone's face for them to experience the smell.

2. The game whereby two or more people try to give each other the Pubic Hand.

That idiot wouldn't shut up, so I gave him the Pubic Hand. Man, I guess I should have showered before the party; you should've seen him retch!!
