Beer Sex is a game that you play when you are road-tripping. You can play with as many people that you can fit in your car.

The first person to see a car with one headlight hits the roof of the car and yells out "beer sex". Everyone else must follow. The last person to yell it out has to take off one piece of clothing and take 10 drinks. The game is over when the driver says it's over.

NOTE: Driving with an Open Container is illegal in many areas, so, yeah, play at your own risk, and driver can't play cause that's how we roll.
