The cry comes from JoJo's Bizarre Adventure, the long-running manga and anime series created by Hirohiko Araki. 'Dora' is the signature attack cry of Crazy Diamond, the Stand of Josuke Higashikata, shouted during his rapid punch barrages in Diamond is Unbreakable. Clips of the barrage spread widely through anime edits, gaming videos and meme soundboards, where the repeating cry became shorthand for overwhelming speed. Its short loop and instant recognition keep it popular for parodies where any fast repetitive action is treated like a Stand attack.
