No, he is bone idle correct. If attraction is all about superiority, you showed her you were superior than her by busting her for turning you (of all the people in the world!) down. Like she is obviously a mental case and deserves no admiration.
Equally, if you don't give a damn what they think of you, it shows that they are beneath you, because frankly, they should give a damn what you think about them, not the other way around. Pick fun at a girl, and she wonders "why doesn't he like me?" and will effectively beg for your attention.

And as for your motivation, don't see getting a phone number as a win lose situation. Consider it as an experiment. Try something, say something out of the ordinary, just to see the response. If it works, then do it on the next girl (again, as an experiment). If it doesn't then don't try it again. This way it is fun, you learn something, your ego and confidance grows, and you come off perfectly not giving a damn what they think. Infact, there came a point in me that I didn't even see girls as targets, but more as a drawing board to try things on.
Hope it helps
