Devil's Dance

When two or more people are having sex and you can hear/sense it.

In 3 lanes of traffic, when two cars in opposite lanes (ie: slow and fast) continuously switch places at high-speeds and come within 2 inches of hitting each other. Used by douchebags (or teens) to piss off all drivers in the immediate vicinity. Pulling this off requires great timing, patience and a LOT of balls. Typically seen in D.C., Chicago, Miami, and New York.
