The name itself comes from Dragon Ball, where Kakaroto is Goku's original Saiyan name, and fans have long used it as a shorthand for the character's more serious, powerful side. Online, short clips built around that name circulate as reaction sounds in gaming videos, anime edits and meme compilations, where the familiar reference does most of the work. Its staying power comes from that instant recognition: even viewers who have not followed every series know Goku, so the joke lands quickly across different edits and languages.
