The line comes from SpongeBob SquarePants, the Nickelodeon cartoon that premiered in 1999, where Mrs Puff runs the boating school SpongeBob can never pass. Her repeated warning became a standalone clip online because it captures his hopeless driving in one escalating shout. Shared on meme pages and soundboards in the 2010s, it moved beyond the show and became shorthand for watching someone lose control in real time. It stays popular because the panic is recognisable even without seeing the original scene.
