A game, invented by me, for couples to play while driving together. It is a simple game, somewhat like slugbug or punchbuggy, but has a fun twist. When they are on the road, they will notice some drivers doing stupid, dangerous, and illegal things (these people are called Jacknuts). When they see these rediculous acts of traffic moronism, they must try to identify whether the Jacknut in question is male or female. If able to determine this, then the game proceeds as follows: When the Jacknut is a male, the woman gets to punch the man. When the Jacknut is a female, the man gets to punch the woman. Don't forget to say "Jacknut" when you punch your significant other (only in the arm, of course). That is Jacknut. It is a simple yet entertaining game which you will never grow tired of playing and since the world is full of horrible drivers, you will have an endless supply of Jacknuts. Spread the word about Jacknut and get out into traffic and start playing!
