The clip comes from the French catchphrase meaning these are not my glasses, they are my nostrils, a line long shared as a joke about a wildly wrong identification. Its humor relies on the confident tone rather than any visual context, which helped it travel easily as a short audio meme. French speaking users repost it on soundboards and in edits, often adding the translated line as a caption, and it remains popular because the setup is instantly understood even by listeners who only catch the final word.
