Short LMAO laughing sound effect of a person cracking up, used as a reaction clip in memes, edits and chats when something is unexpectedly funny.

At under a second, this is a quick burst of genuine-sounding laughter that lands like someone has just read the funniest message in the chat. The laugh starts hard and cuts off fast, which makes it feel punchy rather than long and theatrical. It works because it says what LMAO means without any words at all, turning a text reaction into an audible one. Viewers hear it and instantly get the joke, even if they missed the setup, and creators use that instant recognition to underline a funny fail, an awkward pause, or an unexpected punchline.

LMAO has been standard internet shorthand for laughing hard since the early chatroom and forum era, short for laughing my ass off. As text reactions moved into video, creators started pairing the acronym with an actual laugh clip so the reaction could be heard, not just read. The clip spread through meme edits, reaction videos and soundboards alongside other short laugh reactions like the laughing dog meme. Its brevity keeps it popular today, because it fits between lines of dialogue and works as a complete response on its own.

Drop it right on the punchline frame, not before it, and let the hard cut be the joke. Keep it at full volume for reaction edits, duck any background music underneath, and do not loop it or it loses its snap.
