The phrase comes from Brazilian internet slang, where calling someone a genius of humor is a common ironic reply to unfunny posts and videos. It spread as a reusable voice reaction on soundboards and in short-form edits, especially in Portuguese-speaking communities. Rather than praising real comedy, creators use it to highlight the gap between someone's confidence and the actual result. Its popularity endures because the wording is instantly understood, works without visual context, and fits almost any awkward joke or overacted funny moment.
