As a short reaction clip, dirty oh my god circulates mainly as a shareable sound for short-form video edits and meme soundboards, where its two-second length makes it easy to drop over a reveal without disrupting the pacing. Its appeal comes from the combination of disgust and surprise in a single phrase, which fits messy fails, gross-out jokes and unexpected twists better than a longer reaction would. Because it needs no context to be understood, creators keep reusing it whenever a visual alone is not quite enough to sell the shock.
