With no single identifiable source, this kind of extended laugh has become a staple of online comedy editing, where a long laugh does the work of a laugh track without needing a studio audience. It is commonly dropped into memes, reaction videos and short-form clips to signal that a moment is funny, awkward or absurd, and its length makes it easy to cut under a visual punchline. Because laughter is instantly recognisable across languages, it keeps being reused whenever creators want a simple, human reaction that needs no explanation.
About this sound
A drawn-out laughing sound effect lasting about six seconds, used in funny videos, memes and reaction clips to highlight a joke or an awkward moment.
This is a long, stretched-out laugh that keeps going well past a normal chuckle, rising and falling as if someone cannot stop laughing at something absurd. It sounds playful and slightly over-the-top, which makes an ordinary clip feel funnier and gives the audience a clear cue that the moment is meant to be laughed at. Because it lasts around six seconds, it has enough room to sit under a reaction shot or a punchline without needing to be looped. It works best when the joke is already visible on screen.
