There is no single famous film, show, or creator tied to this short meeh clip, which is part of why it works so well as a generic reaction sound online. Short vocal noises like this circulate on soundboards and in meme edits because they are easy to recognise, quick to drop in, and instantly understood without any context. Here it is used as a shorthand for boredom and mild disappointment, a sound that can puncture hype, mock a weak moment, or close out a failed attempt with a shrug.
