The line comes from SpongeBob SquarePants, where a fish character uses it as a blunt crowd-style heckle. Once the short clip was lifted from the show, it began circulating on meme pages and soundboard sites as a ready-made insult, easy to drop into edits without context. Its appeal has lasted because the joke is instantly clear: a cartoon voice saying something rude in a playful way. That mix of nostalgia and simple, repeatable mockery keeps it in rotation for reaction videos and short-form edits.
