I've been hitting up quite a few parties at my school's Greek village lately, and while I have been having decent success pulling, this problem seems to be a reoccurring one.

How do I keep multiple girls interested, pick out the one or two I find the most attractive and get them to decide that spending the rest of the night with me is better than staying with their friends?

Just to give a quick example I was at a party socializing, doing my usual thing, when a group of 7 Asian girls walks in. Now, I happen to be severely stricken with yellow fever so as soon as the girl I'm talking to waves at one of them and motions for her to come over for the hug I know I'm in. I give her a quick tug on the shirt, let her know I think they're cute and ask for an intro (this girl is a close friend and more than happy to help me hook up with other girls).

I introduce myself to all of them, one by one, and instantly forget all their names. This doesn't really phase me as I can often work this angle to my advantage by playing it off as them not quite being interesting enough to captivate my attention (jokingly of course). I pick out the 2 I find most attractive, HB 8's, and start my flirting. We talk about school, what they think of the upcoming year, events coming up, I up the kino it's going well yadda yadda. My friend texts me they told her they think I'm cute so I figure I'm in at this point and loving the party.

After an hour or so they tell me their friends are getting bored, and I need to try to convince them to stay. I start trying to talk to all of them at once but this proves an impossible task, and the other guys at the party seem to be of little help. They tell me they're gonna go check out another party and I begrudgingly get their numbers, knowing it could have been so much more.

What could I do in the future in the face of a similar situation?
