Space Station 13 is a multiplayer role-playing game set aboard a space station, where the clown is a playable job famous for causing chaos with little more than a horn and a sense of humour. The horn honk became a shorthand for clown behaviour in gameplay videos, streams and meme edits shared online, because it instantly tells viewers that trouble is coming. It remains popular for the same reason: it is short, unmistakable and funny out of context, so creators can drop it into almost any prank or fail clip.
