The phrase is a long-standing Brazilian Portuguese idiom for calling out hypocrisy, equivalent to the pot calling the kettle black, rather than a line tied to one known film or character. As a short spoken clip, it has circulated online as a reaction sound for Brazilian creators and WhatsApp users who want a fast, humorous reply to double standards. Its staying power comes from its everyday usefulness: almost any argument, comment thread or comedy sketch can supply a moment when the accuser shares the very fault they are attacking.
