The phrase is Brazilian Portuguese and translates roughly to my ass is called Marcio, which explains the crude, random humour behind its spread online. No clear original recording, creator or date is widely credited, so the clip circulates mainly as a copied WhatsApp audio and soundboard button rather than as a scene from a film or show. Its short length and standalone punchline made it easy to forward, remix into edits and replay out of context, keeping it in use long after many similar one line audios faded.
