Nelson Muntz is the school bully in The Simpsons, the long running animated series that began in 1989, and he is voiced by Nancy Cartwright. His pointed ha ha, usually delivered while pointing at a victim, became one of the show's most quoted running gags. As clips moved to YouTube, Vine and TikTok, the laugh was separated from the episodes and reused as a universal reaction to failure. It remains popular because viewers recognise the reference instantly, even without seeing Nelson on screen.
