Hey, I see a great PUA future coming in your direction

! Just for the slick responses.. A great style would be practicing the game all the time, to your friends (yes, even the males..), basically to everyone around you.
I will point up a few things from your post with some good response examples

.
"Is that your girlfriend behind you?"
-Oh no.. Already hitting on me are you?! I ain't just a piece of meat, and certainly not that easy
"Oh thats a pick up line, but if it is happy bday"
-I ain't picking you up!, you are just too full of yourself...
As she was sitting, PM me for some funky routines on seated sets. Plus, a great way would have been approaching another babe next to her to bring up your value and make your target notice you, then eject and go for your real target.
And the bathroom part, just walk over and ask for the time, when she answers just say something "Oh, its time to dance!" and take her hand and lead her to the dancefloor.
When she said that "I gave it to him" you could have said "Well I never said you could dance with me.. You just had that kind of a look on your face

"
But now, good night.. Outside running around all the day and now at the computer screen..! Damn I need some sleep!
Good luck

!
