"Ghost riding the whip" — a stunt in which a driver gets out of his car and dances around and on top of the slowly moving vehicle to a thumping hip-hop beat — has gotten at least two people killed, led to numerous injuries and alarmed police on the West Coast and beyond.
A fad among devotees of a West Coast strain of hip-hop music called "hyphy," the stunt has been celebrated in song and performed in numerous homemade videos posted on YouTube.
