Bitchy attitude should be handled with superiority.
I got this tip from David DeAngelo:
PUA: You don't have me fooled for a second there, darling.
HB: what?
PUA: I know that most of the guys you date fall for this laid-back, I'm beautiful, I get what I want-attitude of yours. I'll bet you a dollar right here that I can tell you something that noone you have been met before has told you..
HB: ...
PUA: I know that deep down behind this tough exterior there is a super-sensitiv girl. If someone says something bad about you, you pretend it doesnt bother you, but you'll end up thinking about it for days.. I know that you really are a sensitiv girl, it's just that not many guys get to see that part of you..

And swoop, you're back in the game
NEVER let a girl act like a arrogant spoiled brat without calling her on it in a cool and indifferent way. (creds to DeAngelo for this one

)
