Ghost riding, frequently used in the context of "ghost riding the whip" (a "whip" being a vehicle) or simply ghostin', is when a person exits their moving vehicle, and dances beside and around it. E—40’s 2006 song “Tell Me When to Go” produced by Lil Jon brought mainstream attention to “ghost riding”. Ghost riding is also another term used for car surfing, and the term is also occasionally used to describe a moving vehicle with no occupant, such as when a car without the hand brake applied starts to roll down an incline. The practice originated in Northern California, specifically the Bay Area. It gets its name from the fact that while the driver is dancing beside the moving vehicle, it appears that the vehicle is being driven by an invisible driver.
