Nothing real about this Italian!
Take it from a REAL born and raised Italian!!! This book has been written by someone who barely knows the language and merely translated Brooklin slang into italian words.
90% of those phrases don't make any sense in the culture!!! I've found a lot of misspelled words and serious grammatical errors!
...And by the way, I really would not suggest to get rude if you go visit Italy....trust me, not a good idea!!!
