Heres a routine I came up with the other day, field tested and it works surprisingly well. By the way, im white and arranged marriages aren't a part of my culture, which makes it work even better, because they're not sure if you're lying or telling the truth.

(use when the conversation is framed that she is persuing you)
PUA: Even though im arranged to be married and should be enjoying single life while I can, I prefer not to be treated like a piece of meat!
HB: (hooked blah blah...) what if I wanted to marry you!?
PUA: Then we would have to elope to Vegas and get married by a fat elvis and avoid my family until the dust settles.

I can guarantee this will instantly hook. Every time they will want to know more about this arranged marriage you have. Its great for building attraction too, because it makes you almost unobtainable...and you'd have to defy your families wishes just for her.
