The exact original recording behind this clip is not clearly documented, so it is best known as a circulating reaction sound rather than as a line from a named film or show. Its appeal is simple and visual-free: the worried oh no no sets up an expectation of trouble, and the laughing payoff undercuts it, which is why it travels well in short videos, memes and chat messages where a quick emotional turn matters more than context. Because the joke is carried entirely by tone, it works across languages and keeps being reused for new fails and awkward moments.
