Chinnifer Maniston 

What people on the internet magazines call the overrated, self-absorbed "actress", Jennifer Aniston, who's chin in MASSIVE with a huge head that is too big for her body, has a broad nose, small rounded, beady eyes that have an inward curl, no cheekbones (Her face is FLAT!), and an okay-shaped body. A complete butterface! Other nicknames are Jawnifer, Jennifer Anusstain

Chinnifer Maniston is too busy feeling sorry for her pampered self to consider the suffering of those with REAL problems while Brad and Angelina are helping those in need!

Maniston

A term used in the celebrity gossip community to denote Jennifer Aniston and her manish appearance. Used in a derogatory manner by those who dislike her.

Brad definitely made the right decision when he dumped that square-jawed Maniston.
