One who is so high, he/she can not function. This individual is so high they can only mumble, drule, feel numb, and sometimes can end up crosseyed. He/She is so high they do not make sense in anything they do. They are completly dumb.
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.
