A hostile, violent, and shallow female character based around what a cynical male writer thinks is "female empowerment". Such characters usually dress in some kind of fetish
outfit and beat up a succession of men that leer, make snide remarks, or attempt rape. Despite being "independent", their arcs inevitably include constant angst over how they're not like other women and men just don't understand them.
The film of Barb Wire
involves a woman that dresses like a prostitute and drops a man to a death by gigantic explosion for calling her "babe". Strong independent woman!
