the "dance" you do when you and someone else just start dating. Usually done next to a car or a house door. Maybe you rock your body or you scuff your feet around.
When you’re taking a nasty shit and have to throw up at the same time, the ensuing scramble around the toilet is referred to as the “New Jersey Shuffle”. The act requires one to dismount the toilet without flushing to throw up while looking at one's own shit. The name comes from the fact that this act is almost as nasty as the state of New Jersey.
