I've been lifting all summer, made some progress, and want to start approaching on campus next fall, like day game.

What kind of things work with college girls? Like what should I say, what is appropriate/not appropriate for the environment?

And how do I act if they reject me and then later I see them around on campus/in class/at a party/etc?

And what if the girls tell each other about me approaching them? Is that good or bad?

That honestly is what I'm most worried about since I don't want to be known as the rejected loser or the failed PUA.
