Friendzone
Is a misogynistic term used by males who befriend females for the soul purpose of getting in their pants, but are unable to because the female is either uninterested, dating someone already, or has some other reason.

A person who uses this term usual feels victimized because the girl doesn't dish out, and the female is characterized as being the bad guy for not reciprocating his feelings.
Guy 1: For 2 years I've listened to her problems, comforted her, took care of her when she was sick, been her friend...But she still won't dump her douche boyfriend even though I am clearly better for her. I'm stuck in the friendzone

Guy 2: I know that feel bro, girls are bitches sometimes
