A sexual act involving 6 guys and 1 participant (male, female or any kind of animal). The first guy pisses on the participants face while the second guy flops his penis on the face to wipe all of the pee off. The next guy then blows a hot steamy load on the participants face (this acts as the coat of wax) while the fourth guy flops his floppy wiener on the face to get all of the hot cum off of it. Finally, the fifth guy spits on the participants face (nothing beats a good spit shine!) and the last guy will fart in the face for a real nice air dry effect. The person (or animal) going through the car wash can either crawl, or be pulled through on a skateboard (usually depending on whatever tradition dictates in your region.)
Hey Pete, tell John we should give that girl a California Car Wash later. Do you think we can round up another 3 guys?
