An Unks is a mysterious entity similar the the elusive UNKALUNG and is almost certainly the victim of the politician wannabe uncle at the Thanksgiving dinner, Bigfoot. It can also be a affectionate way or nickname for an UNKALUNG that is a close friend. He is the most Unkish guy you will ever meet and enjoys Monday mornings at your local pub, literally manifesting there where ever it is. He is a great mate and will passionately kill anyone named after a drinking utensil; ie Straw, Straw, or Cup.
Hey, Unks, could you pass that salt

Mary: Did you hear about that new Unks guy that Chadrewick is hanging out with?

Henrikson: Yeah he is so lucky to have an Unks
