Occurs when a driver is first in line at stop light and needs to turn left: The act of, when a stop light turns green, turning across traffic before the motorist facing you at said stop light (who has the right of way) has a chance to go staight through the intersection.
"I was stopped in my car, first in line waiting on a green light when I started adjusting my radio. I looked up, the light was green, and the guy in the car across the intersection from me turned left before I could go straight. I had the right of way. The fucker got me with the Jersey Jump."

When you make a left turn at a light as soon as it turns green, jumping the cars coming the other direction.
