Floriano Peixoto was a Brazilian military leader who served as president from 1891 to 1894, and his formal historical name is part of the humour when it is used for a modern entrance joke.

It spread as a reusable reaction for arrivals and introductions, where the contrast between the serious name and a casual appearance makes the moment memorable and easy to share.
