Be yourself,
Pretty much anything goes with the ladies so if you can think of it do it.
Be funny, or overly, gloriously, satirically romantic.
You just have to have the confidence to do it. If you can't get the confidence think "what is the worst that could happen" its nothing really to be told to "go away you creep" by a girl you don't know, so you really have nothing to lose.
It fits my personality but I've done these before.
...stared at a girls breasts the whole time they have been talking to me so they NOTICE & then when they stop talking or say something about me looking at them (has never happened, most girls will be too polite or not have the confidence to say it to you). I look them in the eyes and say "yeh, they're alright arn't they"
...had a friend introduce me to a random girl, I shake her hand & walk around her in a circle looking at her, and say to my friend, "yeh I'd do that".
They found these acts of horrible sexism against them really weird at first and neither laughed but it instantly set the tone for the rest of the day, & by the end they really liked me.
so basically if you can think of it do it (be confident).
(or if you are a real weirdo & have some ideas that you believe may be a bit to freaky, if you could imagine it happening on the comedy channels then its probably ok to do it!).
Thats how to flirt.
(you could say what "beautiful blue eyes they have" as long as their eyes are BROWN, if they don't notice you said anything wrong, ask them later "do you remember I said... and ask them do they get it! (the joke)"
So be yourself and everything goes!
