Femtrang
A female, usually in her adolescence, who after the first hook-up with a random boy, becomes totally subservient to said boy's every sexual whim. She craves him and will return to him as if she were his personal sex boomerang.
Sonia hooked up with Mark at the jelly bean dance last week. She's hooked up with him 58 times since; she's such a femtrang.
