I was in a similar situation. I was at party and there were two girls and 7 or 8 guys. I went next door and got some girls to come over. 3 of the other guys were big football players who shouldnt have a problem picking up women or being alpha. But, I made them look like kittens compared to me by being the alpha of the group. Being outgoing ( not annoying or loud) but conversational. Slapping their backs and DLV on them by asking them "you guys are football players aren't you supposed to have some girls or cheerleaders around?" There response was just shaking their heads and saying "No".
It seems you were paying way to much attention to the girls. You need to be alpha with the males in order to be alpha with the girls. Make yourself the center of attention by being conversational with them, making jokes and being comfortable in your own skin and not give a fuck. After/while you are winning over the males( the females will notice this because you will be the center of attention) focus on negging your target.
she got shutout in a beer pong tourny and she was bitching and moaning about losing and "im gonna go home"(just to make all the guys go noooooo, stayyy!" ...i on the other hand said "get a ride and take care".
That is a good line. But you sound more like a jerk than a PUA.
I would have said, "man you are horrible at beer pong. You should get some lessons. I would teach you but I am sure you would try and steal my breath taking beer pong skills. You're not a thief are you? Hold that thought while I grab another beer."
Ignoring your target will get you only so far. At first that is neccesary. But then you need to pursue them in the proper manner by using negs, cocky-funny and push pull techniques/time constraints.
*Remember that "piss poor drunk girls" are always prime targets for males and generally they are out of control, meaning they need someone to put them in their place. Be the one to do that.
