hey man. i had that experience too. i understand what is like. but i overcame that problem not by asking myself "what can i say?" the real question "Why can't i just say anything i want?". big difference.
when doing game on a girl it is important about what the girl thinks of you, but what is of great value to her is the opinion of her friends. there's no reason why you can't interact with the friends. connect and get to know them. express how you feel and vocalize your insights and give them a refreshing conversational experience, and make them feel good about themselves. the results will be amazing, not only will they go to the girl you're interested in and tell her how wonderful you are, you may find that they will want to have you for themselves lol.
even with guys, do exactly the same thing. connect, empathy, make them feel good, tell them about some cool stories etc. the result of connecting with the guys will be that they will invite you out more, you will be perceived as the AMOG (alpha male of the group) and the guys will introduce you to some girls they know and they will do the work for you and DHV you.
concluding point: use your natural pua conversational skills on anyone and the results will be astronomical.
hope that i have helped. happy gaming dude
