Eu não sei translates directly from Portuguese as I do not know, and the clip circulates online as a standalone reaction rather than a quote tied to a confirmed show or creator. Portuguese phrases often travel across meme pages, WhatsApp groups and short video edits because they are short, expressive and easy to reuse even for viewers who do not speak the language. This one stays popular as a universal shrug in audio form, reused whenever a creator needs a clear, funny admission of confusion without adding extra dialogue or explanation.
