The laugh comes from Nelson Muntz, the school bully from the animated television series The Simpsons, which premiered in 1989. Voiced by Nancy Cartwright, Nelson frequently uses his clipped “Ha-ha” to ridicule other characters. The catchphrase became one of the show’s most recognizable reaction sounds and later spread through video edits, message clips, and meme compilations. It remains useful because its meaning is immediate even without visual context. Other clips featuring Springfield characters, such as Homer - Ta Gueules, appeal to the same audience for animated television reactions.
