"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. 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 handbrake applied starts to roll down an incline."@en .
