The exact origin of this OMG what is that clip is not clearly documented, which is common for short reaction audios passed around soundboards and meme pages. Its appeal comes from the universal phrasing, as almost anyone might blurt out the line when confused. Because of that, it has become a handy shorthand for disgust, confusion or playful judgment in short-form video, working as a quick shocked reaction. Creators reuse it across short edits, gaming streams and reaction compilations where a short burst of surprise fits better than a longer rant.
