well the first thing that came to my mind was a very simple attribute: it's hot in there right? then I started thinking, isn't it in southern America... that shiiz that people usually don't mention
that, however probably wasn't what you were looking for. The first think that was, that came to my mind, was coffee. I just love coffee, and they grow a lot of it in Brazil right? I'm no pro, though, and the coffee I drink is probably mostly African, although some is prolly from Brazil too, since it's a blend.
I don't watch soccer, so that didn't cross my mind. I do have to say, though, once I read it written by someone else, there does seem to be a lot of Brazilian people in internet games.
