Ke shou circulates as a short soundboard clip rather than a track or scene with a widely documented origin, and its Chinese title points to a cough as its central sound. On meme and short-form platforms, clips this brief spread because they are easy to drop into an edit, reuse as a reaction, and recognise instantly even without context. Its appeal is practical rather than musical: a single human cough reads as embarrassment, disbelief, or an awkward interruption, so creators keep returning to it for quick timing in comedy and reaction videos.
