The clip is credited as coming from Brandon Herrera content, where the exaggerated caveman ugh was isolated and boosted to a loud, meme-ready level. Short grunt sounds like this spread easily on soundboards and in short-form edits because they need no context and read instantly as dumb or confused. The caveman framing gives creators a simple joke about thinking too little, so the sound keeps being reused for mistakes, bad takes and moments where words would be too smart for the situation being shown.
