A term used to vilify women for exercising her right to say no because somewhere along the line men got the idea that women are obligated to date or sleep with anyone who talks to them or who they're friends with, and if they don't they're horrible people.
Bob: Wahhh Suzy put me in the friend zone!
George: Oh forget her! She's a heartless bitch! All women are the same!
Suzy: Excuse me? First of all I can't help the fact that I'm not attracted to Bob like that. Second of all I lost one of my closest friends who it turns out was only pretending to be my friend in hopes of getting in my pants, and I'm the villian here?
