Lots of eye contact, and a good sense of humor will get you far. But listen too!
Sometimes I'll walk up to a woman and say,
"Hello, You seem kinda' like a very interesting person.
Are you?"
Or maybe,
"Hi, how was your day?" / "how is your day going?"
I'm very friendly about it, but also a little ****y too.
It works really well because women are infatuated with themselves.
The most interesting subject to a women is, after all, herself.
Once she starts talking about herself nonstop,
do not worry -- this is normal.
Be cool, it is a sign of high interest level in you.
Just don't interupt her,
or start talking about your sad sad existence prior to meeting her glorious @$$.
If you kiss her @$$, you'll be nothing more than
an emotional tampon for her to use and disguard
(I just love that phrase).
If you walk up to a woman and say,
"hey baby, you make me hard..."
or some asinine remark of that nature as someone suggested a while back,
it will only get you c*ck-blocked.
Remember, if you bring up sex, it will make her feel unsafe,
disgusted, or even threatened.
On the flip side, she can talk about it all she likes.
So if she brings it up, no biggie.
If you wanna' use a crude 'pick up line'
wait until about your 50'th wedding anniversary, and then say something like,
"You and me baby ain't nothin' but mammals,
so lets do it like they do it on the discovery channel."
Oh great, now I have a mental picture of old people...
doing things... AGAIN!
