No clear original source is documented for this ueee clip, which circulates online as a short baby rage reaction sound rather than as a named scene or song. Its spelling tries to capture the drawn out whine in text, so it gets shared as ueee in soundboards and meme edits. Short looping cries like this spread because they need no context to understand, and editors reuse it whenever a moment calls for an exaggerated tantrum, a sore loser moment, or a joke about someone crying over nothing at all.
