breastist
A person usually male who judges another person usually female by her breasts. The stereotype breastist is known for his "the biger the better" attitude that has become almost a cliche, in their world this is given more thought than even what kind of car to drive.
My uncle George Teton used to always say "hey man, look at them _ _ _ _. He prided himself in never saying the same sexist term for the mammillary protuberances and I would just say "yo dude, whatever you breastist".
