The Jiafei slay scream spread as a short TikTok meme sound, passed around in edits, reaction videos and lip-sync style clips rather than as a longer song or scene. Its appeal is its size: at under a second, it is easy to drop into almost any video without breaking the pacing. As creators reused it for slay moments, dramatic reveals and ironic hype, it became a shorthand for over-the-top excitement on TikTok and in short-form edits elsewhere, which is why it still appears whenever a clip needs an instant burst of energy.
