A girl who claims that her sexual encounters were nonconsensual. This girl was usually drunk when she willingly had sex, and then pleads that the guy took advantage of her. When this girl actually gets raped, no one believes her and she looks like an idiot. This is the quintessential converse of "The Boy Who Cried Wolf"
