The exact origin of this clip is not documented, so it is best known today by how creators use it online rather than by a confirmed source. Short single-word reactions spread easily because they can be dropped into almost any video without needing context, and this one became a reusable shorthand for stunned disbelief. It turns up in gaming edits, meme compilations, reaction videos and short-form posts where the joke depends on timing more than explanation. Its brevity also makes it popular for soundboards, live streams and quick chat replies.
