Here's what I've learned this weekend -
When you see your target, make sure to make eye contact with him briefly or get his attention somehow (walk by, bump into him, excuse yourself, smile and walk away). He should notice you just generally being alive.
Then, when he's away from the group or engaged somewhere else open with his friends with very platonic conversation. Have very platonic body language, that means, don't lean in too much, don't make too much eye contact, no kino, etc.
When your target comes back to join his friends and you, change your body language towards him (eye contact, lean in closer, tilt your head slightly when talking to him). His friends should introduce you to him by now, but if they don't, you can just turn to him and be like.. and you are??? or.. so you boys aren't going to introduce me???
After you gauge the guy's interest, after about 5 min, you can isolate him from the group and take it from there.
I think this approach works best b/c you've already created social proof with his friends, you have immediate conversation topics - his friends, and your intentions (you like him) are clear but still open up to interpretation (or are you just being friendly), in fact, I'd actually start out with being fairly friendly and slowly increase the eye contact and get sexier and sexier..
So the three most important points:
1. He should notice you before hand.
2. Open with him not around (whenever possible I always try to DHV by making the guy come to me, even if its to rejoin his friends).
3. The body language directed towards him and his friends should make your intentions clear.
If the above doesn't work, consider the possibility that the guy could just be a douchebag.
Field tested this weekend.
Hope this helps! Let me know if it works
