The difference between guts and balls. Guts is stumbling home reeking of booze and covered in lipstick to see your wife standing in the door with a broomstick and saying "Are you cleaning or are you about to fly somewhere?" Balls is stumbling home reeking of booze and covered in lipstick to see your wife standing in the doorway with a broomstick and slapping her on the butt before saying "Come on fatso, you're next" Either one will get you killed.
