The exact origin of this short clip is not documented, which is common for user-generated soundboard laughter, but its style is instantly familiar online. Written laughter like jajaja is the Spanish-language equivalent of hahaha, and short bursts of it circulate widely in prank videos, reaction edits and meme compilations where a quick human laugh does more than a caption. Because it is brief, expressive and easy to recognise across languages, creators keep reusing it as a lightweight reaction sound for funny, awkward or teasing moments.
