Parei de zuar circulates as a Brazilian WhatsApp audio rather than a clip from a known film, show, or celebrity, and no single original sender is widely documented. The phrase itself is everyday Portuguese for having stopped messing around, which is why it travels so easily between group chats, status updates, and short video edits. People forward it when a joke needs a clear ending, and its direct, chat-native wording has kept it useful as a reaction long after its first shares, especially in Brazilian online humour.
