The sound comes from The Evil Dead, the 1981 horror film directed by Sam Raimi that introduced Ash Williams and the Deadites, demons unleashed by the Necronomicon in a remote cabin. Short demonic lines from the series became easy to lift as isolated clips because they are brief, distorted and recognisable without any context. As horror edits and meme soundboards spread online, this threat survived as a quick shorthand for possession and cursed power, separate from the longer scenes and gore the films are known for.
