The female version of cocksman, i.e. a woman who uses men and knows how to get what she wants. She takes shit from no one and can drink and play as hard if not harder than the guys. Not to be confused with a 'bitch' or a 'slut' although she is often a sarcastic woman who loves sex. She is also skilled in bed and often wears the pants in a relationship. More closely related to a 'player' than any other sexually adventurous female adjective.
"Man I tried to roll my game on Allison all night but she got me to pay for all her drinks then she called me out on trying to hook up with her. She saw me coming a mile away, what a cockswoman."
