The exact original source of tá saindo clã is not widely documented, so online it is best understood as a Brazilian Portuguese meme phrase rather than a line tied to a single show, film or creator. Its appeal comes from the word clã, which gamers and online communities use for a close group or squad, making the phrase an easy shorthand for everybody leaving at once. Shared as a short audio clip, it travels well in edits, streams and group chats where a quick Portuguese farewell feels more personal and funny than a generic goodbye.
