The cry comes from JoJo's Bizarre Adventure, where the villain Dio Brando shouts muda, Japanese for useless or futile, while his Stand, The World, unleashes a rapid barrage of punches. The chant became closely associated with his battle against Jotaro Kujo in Stardust Crusaders and was later shared widely through anime clips, reaction videos and short-form edits. Its rhythmic repetition made it easy to remix and recognise, and it remains a shorthand for overwhelming force, dismissal and confident villainy in anime and gaming culture.
