A woman that takes charge and asks a man out on a date. Usually very assertive when going after someone she likes/wants. Does not depend on the man to make the first real move.
This is in reference to the Amazon tribes of warrior women from Greek mythology. In this society men were dominated by women.
Man#1: "Man, Nicole has been asking me out for the last 2 months, that chick just won't take no for an answer."
Man#2: "She's an Amazon Woman bro. She won't stop till her hunt ends in a kill."
