The title is written in Chinese characters and Bopomofo phonetic symbols that spell out the sound itself, wo wo lueh, rather than naming a character, show or song. No clear original source is attached to the clip, and it circulates simply as a short user-uploaded soundboard button. Its appeal online is its speed and ambiguity, so creators reuse it as a nonsense taunt, a childish tease, or a random non-sequitur in edits and chats where a full line of dialogue would be too long or too serious.
