Happy Wheels is a browser physics game built around characters riding vehicles through deadly obstacle courses, where violent ragdoll crashes are the central joke. Head injuries became one of its most recognisable outcomes, and short impact sounds from those moments were clipped and shared by players making montages and reaction videos. On soundboards the head smash clip survives because it is instantly readable without context, a single second of gore that tells viewers a run has ended badly. Its brevity makes it easy to drop into edits, memes and streams.
