Galo veio is a Brazilian Portuguese expression, with galo meaning rooster and veio being a slang form of velho, or old, often used as a playful nickname for an older man. As a short soundboard clip, it circulates mainly as a meme audio rather than a line tied to a confirmed film or show. Its popularity comes from how easily it travels in WhatsApp chats, short videos and prank edits, where a brief recognisable phrase can be reused as a reaction to many different situations.
