The clip comes from a fan-collected set of ambience and effects linked to Iron Lung, the 2022 submarine horror game set on an alien moon covered by an ocean of blood. Its cramped, submerged dread later became a reference point for Roblox horror game Pressure, where players hide in lockers from passing sea monsters. Fans began dropping the sound into calls and edits while playing, turning the simple warning to find a locker into a running joke for scaring friends who recognise the danger instantly.
