This jumpscare clip circulates online as a generic Smiler stalker scare, shared between horror edits, fan games and short videos rather than tied to one confirmed official release. The Smiler name comes from internet horror lore about a grinning entity that watches and pursues its target, which makes the sound a shorthand for being hunted. Creators reuse the short blast because it is instantly recognisable, fits a four second gap, and signals danger without needing any dialogue or setup.
