The triple laugh has no single famous source, which is part of why it works so widely: three short laughs are a familiar comic rhythm in reaction videos, short-form edits and comedy sketches. Creators reuse it because it is instantly readable, even without context, and because its short length fits the fast pace of memes and social clips. It is often paired with fails, awkward reveals and over-the-top reactions, where a single laugh would feel too brief and a longer laugh track would feel staged. That versatility has kept it in regular use across prank and reaction content.
