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.
À propos de ce son
A short Chinese voice clip repeating da da da nai zi, meaning big big big boobs, used as a crude meme sound effect for jokes and reaction edits.
The clip is a brief, exaggerated voice chanting the Chinese phrase for big breasts, stretching each da syllable before landing on nai zi. It lasts just over two seconds and loops the same boastful rhythm, making it sound like a playground taunt or a drunken shout. There is no music or background noise, just the raw vocal delivery getting louder and more ridiculous with each repeat. Viewers usually hear it as an abrupt, immature punchline that breaks a normal scene and turns an ordinary reaction into a crude joke.
