A term refering to the female genitalia after you have serviced it properly from behind. After 2-3 hours, it should have lost its lubricity, becoming "shiney." A name to call a buddy who reminds you of a "well serviced vagina."
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.
