Dane Cook's Disease, or DCD, is neurological disorder where a person takes on the attributes of actor/comedian Dane Cook. Symptoms include: overexateration of one's movements and speech, beginning every sentence with the words "And everyone does this, right?" and telling long, pointless stories with no punchlines.
Bob: Did you see that guy over there? He was exagerating that really long, unfunny story.
Dave: It looks like he probably suffers from Dane Cook's Disease.
