Irish Hand Gernade
When a girl sucks you off and you bust a load in your hand while she closes her eyes in anticipation for the money shot. You then hold up your hand and count to 3... On 3, you slam her in the forehead with your hand, delivering a custard facial. This often leads to the Zombie.
the little fuck who thought it was cool to steal my word is gonna get an irish hand gernade in his face.
