Go away cornball has circulated online as a short reaction phrase used to call out someone acting corny, cheesy, or trying too hard to be funny or cool. The term cornball itself is longstanding slang for something uncool or embarrassingly earnest, and this clip packages that insult into a single rapid dismissal. Because it is under a second long, it fits easily into TikTok edits, meme compilations, and reaction videos, where creators use it as a verbal eye-roll to shut down a joke, a flex, or an awkward moment without slowing the pace.
