With no clear original show or creator attached to the clip, 100% noo circulates mainly as a user-shared reaction sound on meme soundboards and in short-form edits. Its appeal is its simplicity: the phrase is short, instantly understandable and easy to place over almost any moment of disagreement. That flexibility has kept it in rotation for reaction videos, gaming clips and social edits, where creators use it as a quick verbal veto rather than a quoted line from a specific scene.
