Homer Simpson is the main character of The Simpsons, the long-running American animated sitcom that began as a television series in 1989, with Homer voiced by Dan Castellaneta. His distinctive laugh has become one of the show's most recognisable sounds, quoted and clipped by fans for decades. Online, it spread through meme compilations, reaction videos and short-form edits, where it works as instant shorthand for amusement or poor judgment. Because the character is known worldwide, the laugh still lands even without dialogue or context.
