Good advice above. I do think the way you see and carry yourself is the most important part. Obviously, looks, social proof, a banging career all help as you get into the conversation. Only my take on Fuze is that you should think positively. Instead of injecting negativity by knocking her down, just be secure in who you are. Think positively about yourself, and her initial attitude won't stick to you. Remember, it's not a competition, it's a negotiation with a common goal
Negging probably works, but it can be very obvious. Push pull on the other hand is very effective at hitting her own insecurities. Just act (better yet, be) unphased, give her some more validation and then turn away. And while the jealousy card is a total girl move, sucking face with another hottie in her line of sight works wonders on most girls.
You could also bring a hot, sociable girl friend with you. Does wonders to your perceived value and can make your target jealous if you and your friend get very handsy.
