Rio is known for its culture of ambiguity. Another classic is "let's get together sometimes" (which means "dude, I totally don't hate you so let's be on each other's background social circle but never get together sometimes"). And its friendlier varient "come by my home sometimes to visit". (Don't go. It means they like you, but just don't show up unannounced). Everyone is on about how São Paulo is much more business…

Seems like cariocas are peach and paulistas (people from São Paulo) are coconut.
