The phrase comes from a Brazilian meme that circulated online in 2017, built around the teasing line about a Sherlock Holmes appearing in the Folha de São Paulo newspaper. The Sherlock Holmes reference works because the detective is instantly recognised as a symbol of clever deduction, even when the discovery being mocked is completely obvious. Shared as a short audio clip on soundboards and in edited videos, it survived because the joke is simple, language-light in its delivery, and easy to drop over any moment of fake investigation or sarcastic revelation.
