The Great Cornholio is the alter ego of Beavis from MTV's Beavis and Butt-Head, which debuted in 1993. After too much sugar or caffeine, Beavis pulls his shirt over his head, raises his arms and slips into the frantic persona. The Angry Video Game Nerd, James Rolfe's retro gaming character, helped carry the reference to a new audience through his reviews and impressions. The clip survives online because that one shouted introduction instantly signals hyperactive nonsense without needing any setup or explanation.
