Beavis and Butt-Head first aired on MTV in 1993 as an animated series created by Mike Judge, following two crude, music-video-obsessed teenagers from Highland, Texas. Their snickering and deadpan commentary became a defining sound of 1990s youth culture, helped by reruns, a later revival and countless clips shared online. Today the laugh is shorthand on social media and in edits for immature amusement, letting creators borrow instant nostalgia without needing to explain the joke to viewers who grew up with the show.
