Maybe it already exists, but I thought about it alone.
I think it can be used almost everywhere, and as I mentioned on the subject, can be good on minority girls.
So, when you see a Japanese\Mexican\Russian or any sexy immigrant you go up to her and say:
Hello, my name is Oshik, and I'm wirting my first novel these days. my novel is about a man who falls in love with a muslim woman. (If the target is muslim of course). I don't know much about Islam and I understand that you're a muslim. can you help me to develop the character?
You got the principle? When you ''write a book'', you need some help from the target to help you develop the plot.
If she's Japanese, tell her that the story involved with the Japanese culture and you don't know anything about it.
If she's jewish, ask her about Judaism because the story is about it
What do you think?
