Good post, although a lot of these I've read in the game hahaha. But for people who haven't read them they're good to know.
I use this opener in day game a lot, and rarely get bad responses:
When walking past a girl (or group) in the streets (or wherever basically) try to make some eye contact, then look down at the ground behind her and make a convincing face saying...
PUA: "Hey! You dropped something." (Point towards the ground behind her where she 'dropped something')
HB: "What? Shit what did I drop?" Looks back and sees nothing. Turns and looks back to you.
PUA: "Dropper your smile
"
HB: "Hahaha, you're funny"
PUA: "No actually, I thought you were really cute, and I wanted to meet you."
HB: "Oh thanks
"
Then run whatever routine you have in mind or whatever. Chances are that she's never heard that before.
The key is to make sure that you have put on a convincing face so that she doesn't think you're just fucking with her. If you just said "Hey, you dropped your smile" She'd know that you're fuckin' around, so wait for her to look back as if you're completely serious. Even if you don't make contact before hand it's easy to pull off.
