The line comes from Dragon Ball Z, where Goku uses it while pushing into Super Saiyan 3 during his battle with Majin Buu. The transformation scene became one of the series' most quoted power-up moments, and fans later clipped the dialogue for edits, reaction videos, and motivational montages. Its appeal lies in the simple idea of breaking a limit that already seemed absolute, which fits everything from sports highlights to gaming comebacks. Decades after its original broadcast, the phrase still circulates as shorthand for refusing to stop at a previous best.
