To ghost ride, frequently used in the context of “ghost riding the whip” (a “whip” being a vehicle) or simply ghostin’, is when a person puts the car in neutral or allows it to idle and then the driver (and passengers) of a vehicle exit while it is still rolling and dance beside it or on the hood or roof.

Ghost riding is one of the latest trends to be popularized by hyphy culture, which originated in the Bay Area of California. The act is one of the highest forms of “going dumb” and a representation of the style of hyphy.
