There is no widely confirmed original source for this short clip, so it is best understood as an online reaction sound rather than a line from a known film or show. Its appeal comes from the Brazilian slang itself, with truta used as a friendly term for a close mate, which makes the phrase feel warm and instantly familiar to Portuguese-speaking audiences. Shared in memes, short videos and chat audios, it survives because it is brief, easy to reuse and instantly signals agreement without needing translation or context.
