The phrase is Portuguese for the Portuguese do not pay, and online it circulates as a short voice meme rather than a song or film quote with a widely documented source. Its appeal is the simple stereotype joke delivered in one line, which makes it easy to forward, save to soundboards and reuse out of context. People drop it whenever money, hospitality or generosity comes up, especially in chats where a quick spoken reaction is funnier than typing an explanation or an emoji in response.
