Very good question
But use your brain a lil, think, remember how I said send mixed signals?
I'll give you an example of a complete conversation and number closing, (Feel special and loved) I'll take sitting at a table in the mall.
PUA: Hey girls, My friends overthere and I have been having this lil debate for HOURS and we need females opinion, (sit down) And I can only stay here for 2 minutes because I gotta get back to my friends. So really quick, How would you feel if your boyfriend was still friends with his last ex-gf?
GIRLS: I'll be ok with it/ I'd hate it
PUA: That's reasonable, now part 2, You find out he has pictures of his ex, but they are not bad pictures, just normal ones, what would you do? get rid of them? or talk about it?
GIRLS: I would so get rid of them / I woudl talk about with him (sometimes they go on and on with it, but let's keep rolling)
PUA: The reason I'm asking is because this friend of mine has pictures of his ex, and now his girlfriend is threatened to break up with him, isn't that fucked up?
GIRLS: Yeah, I mean I wouldn't do that, what's the point?/ You're right, but sometimes girls feeling strongly about certain things (They are already qualyting themselves, let's keep rolling)
PUA: I understand, and thanks for your opinion... as long, as we are talking, I gotta ask you guys, are you guys best friends or sisters?
GIRLS: Yes/ We're sisters (Learn to read body languaje, when people's eyes move to the sides, they are lying, if not, they are telling the truth)
PUA: I could totally tell..
GIRLS: Right, how?
PUA: Rather than explain to you, I'll give you the best friends test
GIRLS: (Get excited) Ok, let's do it...
PUA: Let's do it? You mean right here, right now? Girls usually take me out for dinner first, you know (Prizability)
GIRLS: HAHAHA, Noo, I mean the test
PUA: Oh yeah, right... OK (Act like you were about to ask a serious question and instead say soemthing out of place) Do you guys use the same shampoo?
GIRLS: Look at each other in the eyes first
PUA: You guys already passed (Whether they used the shampoo or not), when two people have a connection, they look at each other's eyes before giving an answer NATURALLY...
GIRLS: (Look at each other again)
PUA: You're doing it right now!
GIRLS: (Crack up) (At this point, they may throw you a compliment or show you IOI's, which include "What's your name?" "You're funny", etc)
PUA: (Don't you ask for names yet!, wait for them do ask for yours) (Now here comes the qualification for the girl you like, your target) Refer to her and say "So, she is your best friend, huh?"
GIRLS: Yes, we have met each other for 1 year (2 years , whatever)
PUA: Cool, my best friend and I are like brothers, we are like girls, man, we go up and down everywhere, he just couldn't make it today/ he is looking for something in the stores
GIRLS: Awww
PUA: What, you making fun of me now?
TARGET: Nooo (Childish way)
PUA: I like this girl... Now turn to her friend (Obstacle) Can I have her?... (See the transition here)
OBSTACLE: Sure, haha
PUA: To your target again... Hey do you consider yourself inteligent (YES)... To the obstacle... Do you think she's intelligent?... (YES/NO) If she says "Yes" say "You have such a good friend", if she says "NO" (making fun of her friend), be like "I thought the same thing and laugh)
TARGET: Why?
PUA: Ima play a lil game with you, to measure how intelligent you're (OK), but we have to bet something,,,, like what do you wanna bet, a dollar, a drink (I don't know... whatever you say), Ok, Look, You like starbucks? (I LOVE Starbucks, that's usually what all girls say) Cool, If you win, I'll buy starbucks, If I win, You buy ME starbucks
TARGET: Ok
PUA: Cool, so what I'm gonna do is ask you five questions, and you have to answer them wrong, if you give the right answer to any of the questions, you lose, got it?
TARGET: Yeah..
PUA: OK, What city are we in? (Gives you wrong answer)
What state are we in? (Wrong answer)
What's today's date? (Gives you the wrong answer)
(Here is the trick, in a curious voice) How many was that?
Sometimes they fall and say "3?", if they say 3, then you say,
HA! I got you!
If they say something like 7! (Wrong answer), you say more calmly now "Oh man, you got me, have you played this game before?"
Since they are usually excited cause they thought they had won, they
say "No"
Then you say "ha! I GOT YOU on the fifth one!"
GIRLS: HAHA,
PUA: Cool, now I have starbucks over the weekend (Imply the weekend or tonight or tomorrow, It's important)
Take out a piece of paper, card or whatever, write your name and number first as in Matt's # 512384746, then if you know her name by now write Michelle's #, if not just give it to her, and she will assume she has to write her number down, Then you fold it, and rip it on half, she gets yours, you get hers....
Cool, huh
The build some comfort,
Ask questions like "Where are you from?" "How old are you? "What do you do for a living" etc, the comfort questions
Don't forget to include her friend in the conversation ALSO
Leave the group, after 3-5 minutes
saying "Pleasure to MEET you both, (To the target), Don't forget you have to buy me starbucks..."
How is that for a reply, huh?

Hope it helps, and you get the idea
