The phrase comes from Fist of the North Star, known in Japan as Hokuto no Ken, the post apocalyptic manga that began in 1983 and its 1984 anime adaptation. Protagonist Kenshiro uses the line after striking pressure points, telling enemies they are already dead before their bodies react. Decades later the moment spread online as a meme, often paired with sudden explosions or defeats, and it is still quoted alongside other iconic anime catchphrases like Za Warudo in edits and gaming clips worldwide today.
