The line comes from The Simpsons, spoken by Homer Simpson (voiced by Dan Castellaneta) during a phone call with Dean Bobby Peterson of Springfield University in the 1993 episode 'Homer Goes to College.' Frustrated and out of arguments, Homer resorts to the most childish insult imaginable, which is exactly why it stuck. The clip circulates on meme soundboards as a goofy, low-stakes diss — a way to roast someone without any real bite. Its brevity and instant recognisability keep it in rotation years later.
