Yeah, its Brazil's national cocktail. The remarkable thing is that there are literally millions of variations on this particular drink. But all share the cachaça rum and tons of sugar as main ingredients.

Its pretty much the nuts yo. I have seen it once at a bar I was at, and then I saw it on an episode of Anthony Bourdain: No Reservations, in which they went on the story etc. And then I tried it, and got hooked lol
