The clip is circulated as a short Portuguese reaction sound rather than as a line from a widely known film or show, and its appeal comes from how instantly recognisable the question is to Brazilian Portuguese speakers. Pode falar is everyday polite speech, so the sound works even without context, which helps it travel in messaging chats, meme edits and short videos where a quick spoken interruption is funnier than text alone. Its short length also makes it easy to reuse, and that repeatability is why it keeps appearing as a small, familiar cue for someone about to speak.
