The uploader credit lists this clip as BLUDemon What's that smell, but no verified show, film or artist source is attached to the upload. With only a few hundred plays, it lives as a small soundboard clip rather than a viral hit. Its staying power comes from the universality of the joke, everyone knows the face you make at a bad smell. Creators keep it in rotation for reaction memes, skits and short-form edits because the line needs no context to get a laugh.
