The line is spoken by Squidward Tentacles, the grumpy neighbour in SpongeBob SquarePants, the long-running Nickelodeon animated series about life in Bikini Bottom. As a short, self-contained reaction, it spread through meme edits, reaction videos and soundboards, where its dry sarcasm made it an easy shorthand for calling out overconfidence. It remains popular because the joke needs no context: one weary question is enough to undercut a bold move, much like the SpongeBob sad song is used to undercut a moment with exaggerated melancholy.
