The name shan shen bu comes from Chinese words for a flashing, evasive step, a term used for high speed movement techniques in martial arts fiction and games. Online, the clip spread through soundboards as a compact effect for teleport style dodges, blink abilities and sudden position changes. Editors keep returning to it because it communicates direction and speed without dialogue or music, and because it works at full volume for action or lowered under a scene for a subtle shift. Its brevity also makes it easy to layer and repeat.
