The phrase comes from everyday Portuguese online slang for a repost, rather than from a confirmed film, show or named creator. It spread in the same chat culture as other Brazilian meme audios like Galvão - Acabou and Risadinha de ladrão, where short voice lines become reusable reactions. Its humour depends on recognition: everyone has seen a post arrive twice, ignored the earlier copy and then had to admit it was already there, which is why the clip still works as a quick duplicate warning.

A Portuguese voice clip repeating já foi postado, the line people drop when a link, video or message has already been shared in the chat before.
This is a short Portuguese voice clip built around the phrase já foi postado, meaning it has already been posted. The delivery is plain and pointed, like someone in a busy group chat flagging a duplicate before the conversation moves on. Because the line is repeated, it lands less like information and more like a gentle callout, creating that familiar mix of embarrassment and comedy when a link, photo or video turns up for the second or third time in the same thread.
