used to name a person group of people that you hate in some way.
maybe it is because your principal is a nazi.. or maybe because the people who you get internet service from are all bitches.. or maybe you use it on a group of people that always annoy you in some way
You: Damn, this girl suddenly decided to put me in the friendzone!
Your bro: Don't care about that! Put her in the bitchzone and hunt for someone else!
