Não, gracinha is a Brazilian Portuguese expression used as a teasing, affectionate way to say no to someone being cheeky, and the short clip has circulated online mainly as a reaction sound rather than as a quoted line from a known film or show. Because it is under three seconds and instantly conveys mock scolding, creators reuse it in meme edits, reaction videos and short-form posts whenever a joke needs a quick, playful shutdown. Its appeal is in the tone: firm enough to be funny, soft enough to stay friendly, so it fits everyday banter.
