look up any word, like pussy:
 
1.
Any woman whose primary interest in a relationship is material gain. A woman who cares much more about a man's bank account than she does about the man. Such women usually soon get pregnant in order to attach to her spouse and to ensure alimony and generous child support.

The closest male equivalent is a boytoy, K-Fed or male golddigger.
