This is not a pick up term. (I am assuming is not, got it from BluePrint from RSD). But I had this happen in several occasion at parties.
First, RAS (reticular activating system) is basically something catching your attention. Like if a hot women is walking by, you check her out because she hold a lot of value to you. Or if there is a gunshot and your attention goes towards the gunshot when you her it.

anyways, when in social environment like a party, and all these AFC trying to get with women, and your attention isn't even going towards them, watch them come try and come and try to hook up with you. From there is easy, just pull the trigger and find yourself a room.
Of course, what I mention is assuming your social skills are really good. Is crucial you need to have your social skills down. For example, the party I was just at hanging out with group of people that I never seen before. I was getting amoged by about 3 guys. Handled them all by befriending them. The girls in the group picked up on it. Later on, it was game over.
Don't be that guy who is getting emotionally reactive to amoging. How I handle amoger is just chill with a smile on my face, with stupid come backs. You wanna have fun with it.
BTW, this party I was at, it was like 4 girls, 2 with boyfriends and like 8 guys. Still got laid from everything I learned from pick up. And I should mention, I never met any of these girls before.
