Oba oba oba has spread online mainly as a short, shareable chant rather than as a clip tied to one well-known scene. Its appeal comes from its simplicity: three identical words, easy to remember, easy to shout along with, and easy to drop over almost any clip. On short-form video and soundboard pages, it is reused as a reaction to good news, a win or a joke, where the repetition itself becomes the joke. That flexibility is why it keeps circulating, even without a single famous origin behind it.
