Bom dia meu ovo circulates as a Brazilian Portuguese internet joke that twists a familiar morning greeting into a rude punchline, with meu ovo used as slang for a dismissive, disbelieving response. It is shared mainly as a short voice audio in group chats and short-form videos, where the humour comes from the contrast between polite wording and the speaker's unimpressed attitude. Because the phrase is short, recognisable and easy to reuse, it has stayed popular as a sarcastic reply to morning messages, motivational posts and people who are far too cheerful before coffee.
