While having sex with a girl doggy style, you ejaculate onto a dirty sock (smellier the better) and shove it in the girl's face. You then proceed to roll over her (as if you are a steamroller) and mash her face into the dirty sock.
While driving on the NJ turnpike:
Man #1 - "Wow, it smells awful."
Man #2 - "Reminds me of the time I gave that stripper from Westwood a New Jersey Steamroller."
