To do back flips and dance your ass off like a moron atop a moving vehicle. Just like Michael J. Fox did in the film Teen Wolf. It is usually accompanied by your buddy bumping some loud and obnoxious music from the vehicle's stereo system.
My friend just got a new Chrysler last night and I was teen wolfing up and down the Strip while he was bumping some loud ass music down below, I couldn't really understand what the song was over the police sirens, we went to jail.
