Luiz Carlos Alborghetti was a Brazilian radio and television presenter from Paraná, known for loud, confrontational police and variety shows from the 1980s onward. Clips of his broadcasts were rediscovered on YouTube and Brazilian meme pages, where his exaggerated greetings and rants became reaction staples. Boua tarde is the mispronounced, stretched version of boa tarde that fans quote most. It keeps circulating in WhatsApp groups and edits because a formal afternoon greeting, shouted like a show opener, still reads as instantly funny to Portuguese speakers.
