Mostly used in a bad way and a good way. How? Well a lot of people use it to call someone names meaning they are rude. But the good way is a beautiful wolf. So when someone calls you a bitch just say "yes, I know, I am a beautiful wolf"
HANNAH:HEY BITCH! GET YO BUTT OVER HERE!
Carlie: okay... That did nothing to mean cause bitch means wolf *laughs*
