Dilma Rousseff served as president of Brazil, and her distinctive formal delivery has made short clips of her speaking popular material for Brazilian internet humour. Bom dia ou boa tarde simply means good morning or good afternoon in Portuguese, but the greeting became a reusable meme because it sounds like the start of an official address. Shared through soundboards, WhatsApp audios and short video edits, it is now used less as a political statement and more as a playful, instantly recognisable way to say hello with exaggerated seriousness.
