This is the opposite of a sophisticant. The sophistican is sophisticated in every way and may or may not have all the money in the world to buy the finer things in life, but they are educated, have tact, are cultured, exhibit excellant taste, are well mannered, and can pull it off every time. There is nothing phony about the sophistican.
Charlie took me out to dinner and knew exactly which entree I would enjoy..right down to the wine. I let him order for me because he is the sophistican in this relationship.
