Wario is Nintendo's greedy, moustachioed rival to Mario, and his exaggerated laugh has become one of his most recognisable traits across the Mario and WarioWare games. Clips of the laugh spread through gameplay videos, meme edits and short-form videos, where creators reuse it as shorthand for mischief, greed and cartoon villainy. It stays popular because the sound needs no explanation: even viewers who have never played a Wario game recognise the cackle as a villain celebrating a bad idea.
