The 'wew' exclamation lives mostly in the wild west of meme soundboards, where tiny vocal reactions get clipped, shared and remixed without a clear original source. Variants of the sound pop up in short-form video edits, gaming highlight reels and reaction compilations, usually as a stand-in for mock surprise or playful disbelief. Because it is so short and expressive, editors treat it like a verbal emoji: easy to drop, instantly understood, and flexible enough to fit almost any joke. Its charm is precisely that it belongs to no one franchise, so it never feels dated.
