There is no confirmed film, show or creator behind this clip, which appears as a user-made soundboard sound created by running a spoken wallahi through a voice changer and raising the pitch sharply. That simple transformation is why it spread: the oath itself is widely recognised in online slang, while the squeaky delivery turns it into a joke that needs no context. On soundboards and in short edits it is shared as a quick reaction sound, reused because its brevity and exaggerated tone make it instantly recognisable even to viewers who have never heard the original recording.
