The line comes from Invincible, the animated superhero series centred on teenager Mark Grayson, and is tagged online as a Mark moment. Fans lifted the short exchange for reaction edits because its blunt, understated judgement fits almost any odd clip, and it spread through meme pages and soundboards where creators search for short, recognisable voice lines. It remains useful because the insult is mild, funny and instantly understandable, even for viewers who have never watched the show, making it an easy shorthand for calling out weird behaviour.
