Puxa saco is a long-standing Brazilian Portuguese expression for someone who flatters authority to gain favor, similar to suck-up or brown-noser in English. Adding Miss in front turns it into a mock title, like crowning someone the queen of sucking up in the group. The clip circulates as a short reaction audio in Brazilian chats and meme edits, especially on WhatsApp, where this kind of teasing nickname is shared whenever a friend, student or coworker is caught being overly nice to someone in charge.
