Long strings of LOL and XD have been internet shorthand for loud, unserious laughter since early chat and forum culture, and this clip turns that typing into sound. It has no single famous scene behind it, which is why it works so flexibly across short-form edits, reaction videos, and gaming clips. Creators keep using it because the laugh is instantly readable even without context: it signals that something is funny, cringe, or intentionally overdone. Its brief length also suits fast-paced timelines where a joke needs to land in under two seconds.
