The line comes from Fist of the North Star, the long-running manga and anime series created by Buronson and Tetsuo Hara in the 1980s, where hero Kenshiro says it to an opponent he has already fatally struck with his Hokuto Shinken martial art. The opponent usually denies it, then collapses as the damage takes effect. Clips of the scene circulated widely online, and the phrase became a shorthand meme for a defeat that is certain before it is visible, keeping it popular in gaming edits, reaction videos and anime compilations.
