A state of being that self-loathing people place themselves in when they are friends with someone they want to date. These people assume that the person in question, who is typically a girl, is acting with malicious intent. The truth is, the person who has been friend zoned is mainly the one at fault because they're either not growing a pair so they can ask the other person out, or they're just taking a previous rejection from the person they're pining over by being a friend that will never be more than that--the closest they can be to their love interest.
If you're stuck in the friend zone, it's just as much your fault as it is theirs, if it's not mostly your fault.
Everyone in r/funny is apparently in the friendzone.
