If you have been to the club or live near there, you would have DHV a bit being able to speak of the place.
You: "Ahhh yes, I knew it! You are so and so's friend right?"
HB: Yes, i know him!
You: Good guy, I know him from blah blah, how is it that you know him?
HB: I know him from school (or whatever)
You: OMG, your not that girl who used to beat him up are you?
HB: Hahaha...No!!!!
You: Good, because I'm a lover not a fighter! But I'm a fighter too, so don't try me...LOL
HB: LOL
You: Good sense of humor +1. What was the ocasion for the party? (Notice how I changed the topic?) If she follows and explains with a long answer, you have sucessfully opened her and made her feel comfortable.
Remember, you are a STRANGER to her; however, if you can get a reply you can guide the convo and start building comfort. Good luck!
Peace...
