Though I doubt my buddy made this one up, he has a FANTASTIC kino that can be used immediately after any opener. It combines mind-games (which we all know HB's love) and actively keeps the kino going for a while yet somehow isn't awkward.

Shortly after your opener, try to get the target to extend her hand for a handshake introduction. Its better if she initiates the gesture, but if you do it will still work. Regardless of initiation, the kino occurs something akin to the following:

HB: [Hand extended for a handshake. During typical handshakes, women tend to stick their thumb straight up in anticipation of the shake while men will let their thumb loosely dangle in preparation for giving a firm grip...the social rule for an alpha gesture. Anyways, to understand what I mean picture a girl with her arm extended and her hand in a firm karate chop but thumb sticking straight up. Got it? Good.]

Esperanto: " Are you serious? You are really going to give me a stiff thumb handshake?"

HB: [Confused, uncomfortable, intrigued. Just where you want her]. "Uh, what?"

Esperanto: Your thumb is sticking straight up. I feel insulted. Didn't your mother teach you how to shake hands properly? [Grabs her hand to shake it, squeezing just a little]. "See how my thumb relaxes across your hand?" [Take her thumb and gently press it down over your hand. Now you are holding hands intimately very quickly]. "This is how you shake hands." [Squeeze. She'll squeeze back. I don't think this is an IOI since your frame is one of teacher and student. She's doing what she's told.] "See, much better."

If you are paying attention, you have an extended, funny, intimate kino very quickly. This works well, and there are tons of variations. Humor is a great thing to add, by saying stuff like "With your thumb like that, I don't even know how to approach your hand" [get your head close to it like you are examining her outstretched hand and pretend to try to shake her hand from a bunch of weird angles while you are frustratingly failing at each attempt]. Furthermore, if the target truly digs it, you can continue the kino even further by commenting on all the possible handshakes people use to say hello. You two then practice them, each more outlandish than the last (hands blowing up, weird high fives, etc.). You two laugh. You're building attraction. Taste that? Its pussy.

-Esperanto

that's definitely been done before but it's one that your friend could have come up with on his own as well.. you can't forget that when looking at their thumb you have to raise and eyebrow to add to the confusion

"Taste that? It's pussy"

Hahaha, i defiantly think this will work wonders because it seems to make the initial opening more friendly/playful then "is he hitting me". But that line was GREAT.
