JonTron, the stage name of YouTuber Jonathan Jafari, built his audience with the JonTronShow channel and its theatrical reviews of video games and oddball media, where his habit of erupting into exaggerated disbelief became a signature. Clips of him sputtering through a chain of 'whats' began circulating as standalone reaction sounds on meme soundboards and in YouTube Poop style edits, where the escalating cadence made it endlessly reusable. It endures because few voices sell confusion as hard as his, and the clip needs no setup to land. It sits comfortably alongside other outsized reaction clips like the Emotional Damage meme.
