I've always known it as a 'sex' and the last one to yell it loses an article of clothing (usually not while driving). Also best to play as just a couple.My wife and I play it all the time. And we play the 'slugbug' game that everyone knows. But a one headlighted bug is the ultimate win! All the clothes!
Too bad you gotta sell the vx! We need someone to buy it and then sell it back to you in a few years when you can get another.
