Jon Jafari, known online as JonTron, built his YouTube channel around exaggerated comedy reviews of bad games and movies, where his shocked facial expressions and shouted reactions became memes in their own right. Clips of his outbursts were cut into soundboards, GIFs and remix edits throughout the 2010s, and this drawn-out what the fuck became a staple reaction for disbelief. It survives because JonTron's delivery is instantly recognisable even without video, letting editors borrow his personality for any absurd moment in gaming or internet culture.
