The Great Cornholio is Beavis's manic alter ego from MTV's animated series Beavis and Butt-Head, which became a cult hit in the 1990s. When Beavis consumes too much sugar or caffeine, he pulls his shirt over his head, adopts a wild stare and declares himself Cornholio, demanding TP for his bunghole in the show's running joke. Clips of the character circulated through reruns, fan uploads and soundboards, and the boast survived as shorthand for delusional confidence. It remains popular because the line needs no context to sound funny.
