You Are An Idiot began as an early 2000s Flash animation and website built around three grinning faces and an endlessly looping song. It spread through forums, email forwards and shock sites, and was often linked as a prank that opened pop ups people struggled to close. That notoriety turned the short chant into shorthand for calling someone foolish online. The clip survived the Flash era through reuploads, remixes and soundboards, and creators still reuse its distinctive laugh when they want an instantly recognisable insult.
