The origin of this specific recording is not documented, and it appears to circulate simply as a short Portuguese voice note rather than a clip from a film or show. The phrase você tem manteiga translates to do you have butter, and its humour online comes from that plain, everyday wording being shared completely out of context. It fits the wider habit of forwarding brief, random voice messages in Brazilian chat culture, where a deadpan question dropped into the wrong moment becomes the joke itself and keeps getting reused.
