Joe's a fuckin' lemon squeezer. Every time I walk by his cell he's stroking his cock. Last night he managed to jizz on me before I could get out of the way.
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.
