Jayleens will use you as long as they can, or until you run out of resources, which ever comes first. Jayleens usually feed on money and they have a hefty appetite. When a Jayleen no longer has a use for you, it will discard you like a piece of garbage. It will also blame you for everything that goes wrong in its life, even though you have no control over it. Jayleens are usually female, but they can also be found in the male variety.
