The title is Dutch for laughing audience, and clips like this are widely shared as generic laugh tracks for online video. Audience laughter has long been used in television comedy to signal a joke and cue viewers to laugh along, and the same effect carries over to short-form edits, reaction videos and memes. Creators use this kind of crowd reaction because it is instantly recognisable, needs no context, and can turn a simple clip into something that feels like it was performed in front of a live studio audience.
