The faaaaahhh clip spread as a short meme audio rather than as part of a longer song or scene, which is why its exact origin is hard to trace. Shorter spellings like Fahhh and related clips such as the scream meme travel together in sound libraries, with users searching the stretched spelling to find this specific drawn out version. It caught on because one shout can stand in for shock, disbelief and failure at once, so editors reuse it across gaming, reaction and fail compilations without needing any context from the original post.
