A female that behaves douchy is a bitch.
A kind of douche: a privileged person who doesn't know they're privileged and who thinks in terms of refining a brand for themselves through purchases made with discretionary income. They also adopt and discard opinions in pursuit of their ever evolving brand. One clue to the douche personality: everything they wear is fairly new because they're always tweaking their brand, fiddling with new things they can afford to buy. A douche loves passing tests and going for brass rings, acquiring markers of success. They are self-centered strivers and usually clever and worldly. For them, the world is primarily a place where they can consume and win at status games.
