Used to describe a person who is so pathetically infatuated with a person or sexually desperate that they become so desperate, they actually plunder the meaning of the word desperate.
Ex 1: "That girl will do anything to be with her man that she's being a despirate."
Ex 2: "I think I'm going to hook up with my ex tonight."
A person you hate intensely not because they deserve such hatred but because they serve as a focus for your general hatred. A healthy way to dispense with excess animosity.
Jake's not really that big an asshole. He just serves as my hate sink.
