Get the plum dumbmug. Usually a dim witted blonde with big boobs, named something like Candi or Brandi. She makes basic errors, can not tell right from left and is very gullible. A women who lacks the fundamental skills to live by her self, she has a master to help her through life. A clueless whore that loves sex with anyone.
