Screech comes from Doors, the popular Roblox horror game where players explore a haunted hotel and face a series of entities in dark rooms. The entity of the same name appears when a room is pitch black, giving players only a brief audio cue before it strikes, which made its screech instantly recognisable to fans of the game. Gameplay clips, reaction videos and short-form edits spread the sound beyond Roblox, and creators now reuse it as a generic dark-room jumpscare cue even in videos that have nothing to do with Doors.
