Ok shes the punk type eh? First off, are you knowledgable of punk music at all? Do you like any of those bands? If you do, then i would leave her a comment kinda of negging her like, "You i would think someone like you would have like a lot better bands, (insert band name) sucks! But (insert band name) is decent lol

" Thats assuming you also listen to punk. If you dont, then just neg her in some other fashion. I have dated many of the punk types, as they seem to be my weakness, and alot of them were hott and had that i dont give a fuck attitude. Definately do not compliment her looks. Im sure she gets it all the time and if you do it she will asssume your just another AFC trying to get in her pants. I dont know if its tru of this girl, but many of the hott punks i have dated have very high ASD. This is only at first as most of them are actually slutty, they just dont want you to think that.
If your into punk, then the neggin one of her bands would be a good way to go. She obviously likes punk, so she will be up for talkin bout it. Just move on after you've opened and go with it. May be invite her to a show. PM if you need extra help.
