Building social proof ground up

Alright guys, picture yourself in a lecture room with a couple hundred people. You don't know anyone of them. You're a PUA so you start talking to your target. You have great opening, you start Kino early, and you think you have everything right.

To avoid and intrusive attempt of asking her out, I've noticed that one way is to build up social proof around you and to have friends who will go out with you to party so you can invite her along.

This is especially helpful for beginners because it puts both you and the girl on a low commitment level in terms of energy. You don't have to worry about what to say next and if the convo dies, move to your friends and they'll pick you back up.

One thing I've noticed at this point is that we DON'T have that type of social proof. Our high school friends are long gone and the rapport build with the new kiddos at lecture room don't seem enough for them to not Flake us. These are guys we are talking about not just girls.

What can a PUA do in this situation to build that strong rapport so that there will be "buddies" who will go out with you for you to be able to include the girl?
