A game in which a female wears a low-cut shirt and a man attempts to throw small balls of paper down her cleavage. The female then throws small balls of paper at the male's face. Every paper ball that goes down the girl's shirt or hits the boy's face is a point. Whoever gets the most points is declared champion.
Friend: "Why are you guys throwing balls of paper at each other's cleavage and face?"
Boy: "Oh it's a game called cleavagefacepaperball. The score is 3-5."
