The phrase comes from Brazilian Portuguese slang, where brigado is a shortened, casual form of obrigado, meaning thank you. Online it circulates as a short voice meme rather than a formal recording from a known show or movie, shared on soundboards and in group chats for its rude but playful gratitude. Its two second length and clear delivery helped it spread as a reusable reaction clip, especially among Portuguese speaking users who use it to turn an ordinary thanks into an over the top joke.
