Hater Clone
A person who both idealizes you and secretly hates you at the same time. They mimic everything you do in hopes of gaining the same results, but they hate you because they always seem to fall short. Hater Clones tend to stick very close the 'original' and often fain friendship to have an inside look.
Tricia talks behind my back, but she just bought the same purse that I have, she is a Hater Clone.
