The chant comes from Dio Brando, the flamboyant villain of JoJo's Bizarre Adventure, who shouts 'muda' while unleashing a flurry of punches with his Stand, The World. The phrase became one of the series' most recognisable battle cries as anime clips circulated online, inspiring countless edits, remixes and reaction videos that pair the shouting with spam attacks in games and everyday arguments. Its appeal endures because the repetition is instantly recognisable even to viewers who have never watched the show, especially alongside other JoJo moments like the dramatic time-stop sequence.
