The sound is linked to Big Brother Brasil, where short, expressive reactions are often clipped and shared far beyond the original broadcast. Ai que saco is a common Brazilian Portuguese expression for irritation with something tedious, so the clip travelled easily into WhatsApp chats, TikTok edits and meme videos, where it works without translation for Portuguese-speaking audiences and as a recognisable tone of exasperation for others. Its staying power comes from that everyday usefulness: almost any dull, repetitive or disappointing moment can be summed up by this single weary phrase.
