Ratinho is the nickname of Carlos Massa, the presenter of Programa do Ratinho, a long-running variety show on Brazilian television network SBT since the late 1990s. His loud, populist style produced many short phrases that circulate separately from full episodes. Esse é o meu patrão became reusable online because the line works without context, functioning as exaggerated praise for any authority figure. Brazilian meme pages, group chats and short video edits keep the clip alive as a quick, recognisable reaction to generosity, leadership or a dramatic entrance.
