You're both are right. You know my Italian isn't that good, but I did my bet just after three translations have been rejected.
I know, guilon, the language is vulgar. "É muito boa" also works in Portuguese. Xini, it means something like "she is hot", but with a more indecent bias.
And yes, "prima" is "cugina" - once upon the time, I knew a bit of Italian, but I forgot it almost all. Anyway, this one I can fix myself. Thanks.
