if you cannot hook up with a girl at a frat party, hang up your balls and turn your **** in LOL
You can be very direct at frat parties (I've made out with girls in less that 30 seconds) and I've gotten a BJ from a girl in less that 30 mins (that is also a personal record though so...)
Just go in high energy, high fun. Use high energy material that they can comment on. Ie- jealous GF; gf still has pics up of her ex in her room, etc. STuff they can relate to and talk about then tell a funny story about it THEN CLOSE. After like 10 mins of high energy jsut be like hey its awesome talking to you but I have to get back to my friends, give me your number so we can keep this convo going later. Get a bunch of solid numbers then start working for your ONS. 2 weeks of this and you can have MANY leads
act like you are having the best time... also have SP. that is huge at frat parties. Just go around high fiving and bsing for like 2 mins with everyone then after 30 mins of this you can basically have ANY girl you want. Seriously. Girls in sororities are sheep, be the shepard. BE THE SHEPARD
