The phrase comes from Brazil's CPI da Pandemia in 2021, where businessman Carlos Wizard Martins was called to testify about the federal response to Covid-19. Granted protection against self-incrimination, he answered repeated questions by stating he would remain silent. Clips of the hearing circulated on Brazilian social media and messaging apps, where the formal line quickly became shorthand for any obvious dodge. Its continued use comes from how recognizable the wording is in Portuguese and how easily it fits interviews, debates, and everyday arguments.
