The phrase comes from Portuguese internet humor, where a mock thank you speech became a reusable audio joke for taking credit. The wording thanks the speaker himself, then repeats the same thanks as a second point, which is why Brazilian users share it as a WhatsApp style reaction. It spread through short video edits, streams and meme pages as a sound for smug celebrations, solo achievements and ironic award moments. Its short length and clear punchline keep it useful even for viewers who encounter it outside its original context online today.
