Female equivalent of "douchebag", with characteristics of "hooch", describing a woman that is both pretentious and slutty. She constantly one-ups stories and thinks she's better than everyone else. Specifics vary from region to region, but all in all, this person is a bit of a jerk.
Can be used to randomly insult any female.
That hoochbag made fun of my boots last week, but I saw her wear the exact same ones today.
