Lonely Girl Syndrome
A girl who suffers from a constant need of someone's attention, that they will say or do anything related to social retardedness in order to attain such.

A tender issue to the victim, which will usually result in straight denial if brought up, OR gratification for the attention, leading to another stupid series of social acts.
