The phrase comes from everyday Hindi and Urdu baby talk, where dudu is a childish word for milk and aao mere is an inviting call. No single film, show or creator is confidently tied to this recording, so its history is mainly online rather than in a credited source. Short voice clips like this spread through soundboards, group chats and short form edits because the words are easy to recognise even without translation. It stays in use as a light teasing sound for hunger, cuteness and mock complaining.
