The kind of things you'd expect... to act confident even if you don't feel confident. Try to have subtle physical contact so you don't get friendzoned. Try to get them talking about themselves like ask them questions as opposed to talking about yourself. Try to get them to seek validation from you by "negging" them https://www.urbandictionary.com/define.php?term=Negging . The last point i vaguely remember is if there's a group of girls to give attention to the girls you aren't interested in so that the girl who you are interested in feels left out and wants your attention. After a bit i started really disliking the whole thing because it really takes the emotion out and makes the whole thing feel very robotic. Not to mention i've never been into one night stands.

Oh and there was thing called DHV.. demonstrating high value... but again that's just really common sense things.
