This is what I usually do...
Tell them I need a beer pong partner, ask them if they are any good. They validate themselves, I respond with a "You better be good." While playing, neg them about their posture when they shoot, ask them if they know how to play the game when they miss (small negs). Stand close, but not too close. If you win, get a hug and tell her to come chill on the couch/outside. If you lose, blame it on her and continue negging. Sit on the couch or go outside without asking her to join you, she will probably follow if interested.
This is assuming the party you are at has beer pong, which most college parties do.
