Where a guy is driving down the road and the girl decides she doesn't like what he just told her, so she threatens to NUT PUNCH him in the balls. This can only be accomplished while the guy is driving and not standing up.
While Kasey and Dale were driving down the road, Dale made a smartass comment and was nut punched by Kasey.
