Gustavo Mendes is a Brazilian comedian who became widely known online for his parody of former president Dilma Rousseff, turning her speech mannerisms into a recurring comic character. Short lines from that impersonation were widely clipped and shared as reaction audios in Brazil, especially on WhatsApp and meme pages. Como assim became one of the reusable phrases because it is an everyday Portuguese question that fits almost any surprising situation. The clip continues to circulate as a quick, recognisable shorthand for disbelief in Brazilian internet humour.
