That Was Funny. Some days ago, I watched on YouTube a funny advertisement. In the advertisement there were three american scientists which was watching videos about Brazilians. In the videos Brazilians were speaking some of most frequently used slangs in Brazil. Those slangs were "eita" and "mano do céu". I'll try to explain those slangs. Eita is a slang that does not have a meaning, even in portuguese. It is just a slang or expression that brazilians use when they are surprised or astounded about something or someone. Mano do céu has a meaning but it does not make sense. Mano do céu literally means "brother from the sky". The slang "mano do céu" as well as "eita" is used for brazilians when they are surprised or astouding about something or someone. Let me give an exemple: Imagine that you have a friend and you know that he does not have money. One day he came to you and said "I bought a Ferrari". In that situation, a Brazilian could say "eita" or "mano do céu". Now you can ask: What was that advertisement about? That advertisement was about a chocolate company. While the american scientists were trying to understand those Brazilian slangs, a storyteller said: Brazilians have to be studied (because they use slangs that does not make sense). Also, the storyteller gave an explain why Brazilians use those slangs, brazilians have cocoa, the feedstock of chocolate.
