"Alex, you numb nut. Why did you bang HER?" OR "GODAMIT Jeff, you NUMB NUT! Why don't you go fuck a tree while you're at it?"

A game of you and another player competing to bruise, damage, or hurt the other players genitals. The game begins when one player makes fun of your millimeter peter and you declare war on the future of your children. The winner is declared by whoever lasts the longest or when the opposing player surrenders. The rules are simple: no girls allowed, period. This game is much more intense (and fun) when played in a pool or a place with water.

A Numb-nut is a light-ish insult that you would call a person who does something stupid, or is stupid. Calling someone a Numb-nut is the equivalent to calling someone a dumbass or moron.
"Oh my gosh, you numb-nut! Why would you do that??"
