Rhea Ripley is an Australian professional wrestler in WWE, and Mami became her widely used fan nickname during her dominant run with The Judgment Day, where her confident persona and crowd reactions made the name stick. Clips of the chant and her entrances spread through wrestling TikTok, reaction videos and short edits, where fans reused the sound to signal toughness and attitude. It remains popular because it is instantly recognisable to wrestling fans while still working as a general hype cue for confident characters and comebacks.
