when a person let's one rip, but it sounds like a dog bark
kenny would come into work every morning, squat like he's trying to push out a log, then before you know it, "BARK , BARK " would come out of kenny's ass. within seconds old man Don would walk up front and say " who let the dogs out!" kenny would reply " hi don! that was only a fart bark!"
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.
