The phrase is written in Chinese as da da da nai zi, with the repeated da characters emphasizing size in a deliberately over the top way. No clear original source, creator, or release year is documented for this two second recording, so it circulates mainly as a standalone soundboard clip rather than a clip tied to a known show or film. It has spread through short meme edits and chat shares where a blunt, non English punchline is funnier precisely because the rhythm and tone are easy to understand even without translation.
