I live in New Jersey.  But unlike 98% of the population of the state, I am neither Italian, Catholic, nor Jewish.  I live nowhere near the Parkway.  I don't wear cologne or body spray, and I've never gotten a spray-on tan.  Nonetheless, I'm a New Jerseyan, and this is a short list of what my people do: 

Jersey Salute - Giving someone the finger while driving, likely as a result of something they did wrong.
Jersey Bump - Gently hitting (a.k.a. love-tapping) the car in front of you and behind you while parallel parking.
Jersey Crawl - Not coming to a complete stop at a stop sign.
Jersey Jump/Scoot - Making a left turn as soon as the light turns green, cutting off a person moving forward in the opposite direction.
Jersey Shuffle/Slide/Sweep - Crossing three or more lanes of traffic without pausing, usually to get to an exit.
Jersey Massage - Beating someone with your fists. #sociology
