Thats exactly it. And not only that, I've found that so long as you "do the right things" while not really caring about the results works much better. For example, I was at a club this past Saturday. I saw lots of hot girls there, and must have seemed interested in many of them, because they pretty much wouldn't give me a second look. But there was a girl there that was somewhat eyeing me. Pretty cute girl, but for some reason I just didn't care at all. She ended up coming over to flirt with me a bit, and again I kind of blew her off. I would talk to her a bit, but just didn't care really.
She came up to me later, and gave me a nipple twister out of nowhere. ?

I was confused, as shit. All my friends said she was just a cock tease. So I walked up to her and said, "hey that was pretty inappropriate of you, if I did that I'd get kicked out". She opened up her shirt (had a tank-top on underneath) and said go ahead. We talked a bit, I was just cocky and didn't really care about the outcome, I turned around for a second, and when I turned back she handed me a beer she had just bought for me.

First time a girl has ever flirted with me, and bought me a drink.
So not really caring about the outcome, and kind of doing the right things is what worked for me in that situation. You can do this pretty much anywhere, with almost any girl. Some will take it differently than others though.
