Laughing sounds have long been a staple of comedy editing because laughter is instantly recognisable and needs no explanation across languages or cultures. Online, short group laughter clips are reused in memes, reaction videos, prank compilations and gaming highlights to underline a joke or soften an embarrassing moment. Their appeal has stayed consistent as short-form video has grown, since a few seconds of genuine-sounding laughter can turn a simple clip into something that feels shared and funny, even without context.
