(I'm long winded so I apologize for the length)

Alright so I have used this before with pretty great success. IF this has already been developed and I haven't seen it, I apologize for not being informed and not giving props, however I did arrive at this routine by myself about a year and a half ago out in San Clemente, California.

So everybody has seen Meet the Parents. At the end, Robert De Nero, the former CIA agent father of the soon to be bride, tells Gaylord Focker (Ben Stiller...and hence the name) that he is trained to tell if someone is lying by holding someone's hands. Anyway, this is going to work very well if you have been talking to the chick for a little bit through-out the night mainly so you have material to work with. However it is you lead up to getting her hands in yours is entirely up to you. I was in the military and really WAS put through some intel courses so I always had some bullshit, believable story to use when we got on the topic of me being in the Marne Corps and convince her that the movie is real and that I can prove it to her.

Once you get her hands, place your thumb on the top of her hand toward her wrist and then place your fingers on her palm, with the exception of your pointer finger which needs to be on her wrist to "sell" it. While you’re doing this make it seem believable and take your time because you "want to get it exactly right". You don't actually give a shit, but you want to make her think that you do even if she isn't buying into it at first. Think of it like a magic trick. Nobody gives a fuck until the end when the girl is floating in the air, but everything leading up is completely necessary.

Tell her that the way this works is by measuring her heart rate (don't say heart beat...it confuses the slow pretty ones for whatever reason) and that she needs to keep eye contact with you so you can see her pupils. It is a very common misbelief that your pupils dilate when you’re lying so she will most likely believe you.

Now tell her that you have to ask her some control questions. Anyone who has ever been polygraphed or gone through a VSA test will tell you that control questions are important. Again, it's for show, but do it with confidence and she will follow you even if deep down she thinks you're full of shit.

Control questions are easy. Here's what I ran on an HB8 one time:
Me:Is your name HB8?
Her:Yes
Me:Do you have horses?
Her:Yes
Me:Do you live in shithole county, where ever, USA?
Her:Yes

Now tell her you're going to ask her another question, but that she HAS to lie to you so you can see what her physiological response is. I usually do hair or eye color. Name works. Any question that she is going to say "No" to that you can come up with on the spot. The no answer is important so you can confuse her later. This is your "reset" question. Basically it's going to allow you to move through this easily and play with her emotions. Like a clicker for a dog when it's in training.

Me:I am going to ask you another question, but you have to lie to me.
Her: Haha. Okay.
Me:Do you ever drive over the speed limit?
Her:Of course, everybody does blah blah blah...
Me:Yes or no? (she'll probably fuck it up but remind her she has to lie)
Her: Haha no.

Tell her that now that you have the controls done, you know EXACTLY what happens when she is lying or telling the truth. Most likely, she'll blow it off, but you need to remind her to keep contact with your eyes for the next questions or you'll have to start over. Ask her 3 BS questions and then ask the "reset" again.

Me: Are you 24?
Her: Yes
Me: Have you ever been skydiving?
Her: No
Me: Do you drive a whatever kind of car?
Her: Yes
Me: Do you ever drive over the speed limit.
Her: Yes, wait, no. Haha

She will have forgotten almost guaranteed, but that is a good thing. You have tricked her brain into paying attention to two things now: Your eyes and your questions. She will be so overwhelmingly focused on those two things it'll block everything else out because she wants to win what she sees as a game.

Ask more questions if you want and throw another reset in if you really feel like prolonging it. Usually I use the laughter from the first reset to transition into the last phase.

Get a very serious look on your face. Not morbid or scary serious....mother fucking 50 Shades of Gay sexual serious. If she's still laughing she'll probably stop. Stare right in her eyes. Lower your voice but don't whisper, important I'll explain, and ask her these:

HB8
Me: Have you ever fallen in love?
Her: Yes
Me: Have you ever taken a risk?
Her: Yes
Me: Did you know your heart is beating really fast?

She may not answer. This particular HB8 didn’t because she was caught so off guard. What you have done is over loaded enough of her senses that chances are her brain can't keep up with it. Whether her heart is beating fast or not doesn't matter because she has become aware of an involuntary motor system and is now paying attention to that on top of the other crap so it SEEMS that her heart is actually beating faster because she notices it and because you told her it was.

I like to let go of one of her hands and gently place her hand on my hip while holding her other hand still. I then take my free hand, move her hair out of the way to behind her ear, and lean in towards the ear. Make sure it's a looooong drawn out hair moving. I like to run my fingers gently down the neck also to give her that tingly feeling. Whisper right in her ear that her heart just got even faster when you moved towards her, grab her hip, pull her in, and be a man. I have yet to get that far and not get a kiss close. But trust me when I say, it isn't me that caused her to kiss me. It's her brain.

Essentially, you've overloaded her sense of sight, hearing, and touch and then confused her when you forced her to focus inward instead of outward because it’s unnatural and requires more brain power. When that happens, the brain dumps a small amount of adrenaline which increases her heart rate, causes slight tunnel vision, and initiates the "fight or flight" because it is desperately trying to keep up. But you have the upper hand on the brain. You're holding her hands, not hard, but firm enough that she can't just pull it away. So flight is basically out of the question in quick decision mode because the brain doesn’t think she can get away.
Pretty much, enjoy your make out session. This goes a hell of a lot faster than what this looks like here. I’m just very long winded when I’m typing usually. It should really take 5 minutes at the very longest unless you mix some other stuff in there. Don’t over-do it though because the reset will only work a couple times before it becomes a memorized answer which is bad. You want that laughter in there for the dopamine dump when she messes it up before you force the adrenaline rush.
Tweak as you want and I’m open for advice, but again I have field tested this and it’s a pretty solid kino/kiss close. I don’t advise using this in clubs or loud bars. I’ve tried it and it always ends up with you asking each other what the other one said. This works very, very well when leaving the bar at the end of the night. I would keep it in your back pocket if you’ve been talking to a girl, but haven’t been able to, or haven’t had the time to, kiss her yet before she leaves or before the bar closes. Also, you should really try to lean up against something. A wall, fence, or railing is perfect. This is going to keep your elbows back and pull her in closer to you.
