The phrase comes from Fist of the North Star, the 1980s manga and anime series starring martial artist Kenshiro. He often says it calmly after striking pressure points, moments before his enemy collapses. Decades later the line resurfaced online as a reaction meme, paired with stills, edits and other famous anime phrases like Za Warudo. Its mix of deadpan delivery and over the top consequence made it easy to reuse far beyond anime fandom, and it remains a shorthand for a defeat that was already sealed.
