Bill Wurtz is an American musician and video creator who first gained attention on Vine and YouTube for ultra short musical jingles and deadpan explainer videos. His longer works, including history of japan and history of the entire world, i guess, made his flat delivery and surreal non sequiturs widely recognisable. Short extracts like this single word are clipped and shared as reaction sounds because they work without any setup. The corn clip follows that pattern, turning an ordinary word from his catalogue into a reusable meme punctuation sound.
