Arregou comes from Pânico na TV, a Brazilian comedy television programme known for irreverent sketches and catchphrases that travelled well beyond broadcast television. The word itself is Brazilian Portuguese slang for backing down or chickening out, which gives the clip an immediate, teasing meaning in everyday conversation. Shared widely as a short meme sound, it became a quick reaction for moments of cowardice, hesitation, or a failed bluff, especially in Brazilian online humour and messaging chats. Its brevity and clear attitude keep it useful long after its television moment, because one shouted word can summarise an entire joke.
