The XD emoticon has long been used in chats, comments and memes to show loud, squinting laughter, and this clip turns that written reaction into sound. Rather than coming from a single identifiable show or film, it circulates as a short reaction clip that creators reuse whenever a joke needs an instant laugh track. Its appeal is its brevity and familiarity: almost anyone who has used messaging or social media recognises XD at a glance. That shared shorthand keeps it useful for quick edits, reaction videos and playful teasing between friends.
