it's an abbreviation for Dumb Cunt. For people like me, who use the word cunteveryday, it makes it less 'offensive' and more fun to call someone in public
person one: "My math teacher gave us a project due on the last day of school!"
person two: "what?! she is such a DC!"
DC is the host of the comedy podcast, The Pub Show. DC has been dubbed the PubCrew's "ringmaster" as he often attempts to keep The Pub Show on track and mold it into an enjoyable mix of intellectual conversation and drunken banter. DC is the guy that always has to explain everything, attempts to shelter the listeners from that which might be offensive, and tends to be indecisive about topics discussed on The Pub Show, unless they're REALLY important to him. He would rather let Mr. Super Fantastic and Abe Froman beat each other senseless to prove their points and then agree with whoever wins.
