The cry comes from JoJo's Bizarre Adventure Golden Wind, the fifth part of the series adapted as anime in 2018, where Giorno Giovanna and his Stand Gold Experience repeat muda, meaning useless, during rush attacks. The word mirrors Dio's own cry and contrasts with Za Warudo as another iconic JoJo battle sound. Clips spread through anime edits and soundboards alongside Giorno's Theme and the To Be Continued meme ending, and the solo version became handy because editors can build their own barrage timing instead of using a preset rush.
