This is from my own experience watching my sarge buddie get numbers from asian girls in a college campus
1. Get up in their space: If you see one sitting down at a table you go and sit right next to her. You need to shock them. Don't be asking for advice, opinion or any of these openers. You need to go right up to them and chat them up like if you know them already.
2. Start chatting her up right away: They are going to be a little shocked by you which is good. The shock is going to be a positive one as long as you start chatting her up right away and not let it get silent. You need to keep a constant stream of chatter coming out of your mouth.
3. Start asking her about stuff: Start having a conversation, do light kino.
4. After you talked to her for about 3 or 4 mins or so tell her you gotta go see your friend, hand her your phone, tell her you'll give her a call so maybe you could meet and do something.
My buddy is really not into theory. He even refused to have any game plans other than having lots of confidence and just sitting right next to them. He would just go up to asian girls (all he did) and just get up in their space and start chatting them up. No game plan, no set up lines, he would just chat about whatever he felt.
Sometimes he would get 4 numbers a night. He proved that you don't need fancy lines, game plans etc. Shocking girls with your confidence in getting in their space and chatting them up is probably the whole secret.
