Proposal: The Art of Pick Up
I know there are many aficionado pickup artists, but what, exactly, is a professional one? Who pays people to pick up women? Perhaps some sort of confidence man?
Much as I will regret answering this, a 'professional pickup artist' is one of the guys who make money by offering 'courses' or 'training' on 'pickup strategy' and make money that way. So one step up from gigolo. Just one.
