The phrase um monte de bosta is Portuguese for a load of rubbish, and in online use it functions as a compact, dismissive reaction rather than a quote from a single well-known film or show. Short voice clips like this spread through Brazilian meme and reaction culture because they are instantly recognisable in tone even when the listener only catches the attitude, not every word. Creators reuse it to punctuate disappointment, failed expectations and absurd claims, and its two-second length makes it suited to short-form video, streams and chat replies where a quick judgement lands better than a long explanation.
