May offend Italian to English Art/Literary Cinema, Film, TV, Drama book on film director

I am translating a text regarding a person who gets in with the wrong crowd, the outcasts of the area, plays cards and gambles etc. This person, highly educated, attaches nicknames to many people he meets, and I am having trouble translating these. The problem is the difference between Italian and English in this respect - Italian manages to be so eloquent and almost cultured while being vulgar (!), while a literal translation would not work in English, we are so much more direct :-) Would you leave the Italian and give an approximation in English, or give an expression which an English speaker would use in such a context with reference to this person? Any help would be much appreciated. Thanks!
