The shout is closely associated with Kenshiro, the hero of Fist of the North Star, the manga series that began in 1983 and its 1984 anime adaptation. Kenshiro delivers the rapid cry while using his Hundred Crack Fist technique, unleashing dozens of punches in seconds. Clips of the attack were shared widely on video and meme sites in the 2000s and 2010s, turning the cry into a standalone reaction sound. It remains popular because the reference is instantly understood, even by viewers who have never watched the series.
