The phrase ah, eu não sei is everyday Portuguese for ah, I don't know, and this short recording circulates online as a standalone reaction clip rather than a line tied to a confirmed film or show. Its popularity comes from how universal the moment is, so creators reuse it in WhatsApp chats, short videos and soundboards whenever someone is caught without an answer. Because the delivery is clear and brief, listeners understand the meaning from tone alone, which helps it work even outside Portuguese speaking audiences.
