Über diesen Sound
A deep voice stretches out a playful threat, telling a clown it is about to die, in a clip lasting about two seconds. The slow, confident delivery feels like a cartoon villain making a grand entrance, so the menace turns comic instead of frightening. It comes from Among Us meme edits, where an imposter uses it while cornering a crewmate.
