How to pick up a girl

Not sure why it's hard for guys to pick up a lady. B.I.G. explained early on:

Straight up honey really I'm askin'
Most of these fellas think they be mackin' but they be actin'
Who they attractin' with that line, "What's your name, what's your sign?"
Soon as he buy that wine I just creep up from behind

And ask what your interests are, "Who you be with?"
Things to make you smile, what numbers to dial
You gon' be here for a while, I'm gon' go call my crew
You go call your crew, we can rendezvous at the bar around two
