The phrase comes from everyday Brazilian Portuguese slang, where ta is a shortened form of esta and ne is a tag asking for agreement, similar to right at the end of a sentence. As a standalone one-second audio, credited on the soundboard to creator klayn, it spread less as a quote from a specific show and more as a reusable reaction, shared between chats, short videos and meme edits whenever someone says or does something that sounds completely out of line.
