This sound is most closely associated with the Grudge horror franchise, especially the unsettling vocal rattle linked to the ghostly figure in Ju-On and its English-language remake The Grudge. Online, it spread because the noise is instantly recognisable even without visuals and can make almost any clip feel haunted. Creators still use it in horror edits, prank videos and ironic meme posts because a single short croak is enough to signal dread, suspense and an incoming scare.
