Sacanagem is Brazilian Portuguese slang for a prank, a dirty trick or mischievous behaviour, which gives this clip its punchline even for listeners who do not speak Portuguese. The sound circulates online as a short meme audio rather than as a line from a widely identified film or television show, and its exact original recording is not clearly documented. That ambiguity has helped it travel, because creators can reuse the repeated refusal for almost any joke about being tricked, caught out or watching something go wrong.
