The sound comes from Giorno Giovanna in JoJo's Bizarre Adventure, where "muda muda" is used as an attack cry during rapid strike sequences. Clips of these JoJo rush attacks spread widely through anime meme culture on YouTube, TikTok and short-form edits because the repeated shout is instantly recognizable and easy to sync to visual hits. It remains popular for power-scaling jokes, overkill punchlines and dramatic edit transitions, much like other anime meme sounds such as goku drip.
