Beavis is one half of Beavis and Butt-Head, the MTV animated series created by Mike Judge that premiered in 1993 and defined 90s slacker comedy. His staccato heh-heh laugh became one of the show's signature sounds, endlessly quoted and remixed online. As a meme, the laugh works as a universal reaction to stupidity, mischief and schadenfreude, which keeps it circulating in short-form edits decades later. Like the Emotional Damage meme, it thrives because the delivery is instantly recognisable even without context.
