According to nature, it's in the mating dance.
Our pick-up equivalent is having a framework. We smoothly transition through the framework, while avoiding attraction killing behaviors.
The human mating dance involves a combination of attraction spiking behaviors, touch, and becoming socially accepted by her.
There are different theoretical frameworks out here, but they all center around aspects of attraction, social comfort, and kino escalation.
Frameworks give you natural styles that become part of your lives. The portions of it that involve conversation to make women socially accept you can be used regularly with everyone in your life.
Inside of a framework you'll have some main goals or points that you keep in mind and you do whatever you like that is appropriate for escalating through the framework.
The one I use... I adapted from Justin Wayne which aims to form a romantic connection belief system into the women's sub-conscious and conscious mind as fast as possible. When that's established sex and relationships are a given.
Having my mating dance established allows me to study as much pick-up theory as I want. I then just test it out within my framework to find improvements for efficiency. All of game fits into my framework, as well as anything related to persuading and/or influencing people in general.
This frees me to study fields like interrogation, or negotiation and create new never before seen techniques like this one:

Remember, pick-up is still in it's infancy.
As of this post I'm attempting to incorporate the teachings of the book Models into my framework mating dance.
