Rush is one of the best-known entities from Roblox Doors, a horror experience released on Roblox in 2022. Its warning sound became recognizable among players because it signals a brief window to hide before the entity rushes through. Outside the game, creators started using the audio in shorts, memes and reaction edits to represent sudden danger or an incoming scare. It remains popular because even people who have not played Doors can read the sound instantly as a cue that something bad is about to happen.
