All these other definitions are wrong. The REAL definition is:

(n.) a girl who used to be obsessed with you, but somehow you(either by ignoring her, telling her off, fucking her friend, etc.) got her to "jump off" your dick. Usually happens when you realize she has a disease, she's crazy, or super ugly.
