This particular clip has no widely documented original video or creator attached to it, so it is best understood as a piece of internet sound culture rather than a quote from a show or film. Its appeal is the simplicity of the repeated syllable, which is easy to recognise, easy to loop and easy to reuse across short videos. Because it carries no specific meaning, creators can apply it to almost any playful situation, and that flexibility has helped short, nonsensical vocal sounds stay popular as reaction audio.
