Online, lol laughter has become shorthand for finding something uncontrollably funny, and this long version leans into that exaggeration rather than a short chuckle. It circulates as a reaction sound in short-form videos, streams and meme edits, where the length itself becomes part of the joke. Similar high-pitched reaction clips, such as a chipmunk laugh, are used in the same way to push a moment from amusing to absurd. Its appeal is simple and repeatable: anyone can recognise the feeling instantly, drop it onto almost any funny scene and let the laughter do the commenting.
