The exact origin of this short multo clip is not documented, so it circulates mainly as a reusable soundboard and meme sound rather than a famous movie or show quote. Online, creators treat the single word as shorthand for a ghost appearing, which makes it easy to drop into unrelated videos without any setup or explanation. Its popularity comes from that flexibility, working equally well for horror edits, ironic haunting jokes, and quick reaction posts where a normal moment suddenly turns spooky.
