Beavis and Butt-Head debuted on MTV in 1993 as the creation of animator Mike Judge, and their snickering laugh became the show's signature sound almost immediately. The pair's couch commentary on music videos made the series a defining piece of nineties youth culture, and the laugh followed them into movies, revivals and endless clips shared online. On soundboards and in memes it survives as shorthand for juvenile mockery, a quick audio cue that frames whatever precedes it as gloriously dumb without needing any further explanation.
