they key is to compliment girls on things normal guys don't
afc : "you are so pretty"
pua : *looks a bit distracted when listening* "im sorry, what did you say? i was lost in your beautiful blue/green/etc eyes."
(compliment eyes in general but this one above is a killer

)
pua : "you have an incredible smile"
afc : "you look really hot"
pua : "wow, i really like that dress/skirt/top/etc. youve got great style"
afc : "hey i came over to talk to you because you looked cool and fun"
pua : "hey, has anyone ever told you you have an incredible glow about you? I can tell you like to have a good time"
then off the compliments can come some negs...
"wow, i really like that dress/skirt/top/etc. youve got great syle. Oops, your dress is a little off though *fix imaginary problem* there ya go."
"you have an incredible smile! But did you have a salad at dinner? Youve got some green stuff in your teeth"
"hey, has anyone ever told you you have an incredible glow about you? I can tell you like to have a good time. But hey dont get too crazy, i heard you were a mess the other night at blahblah"
etc
