Top Definition
A really attractive boy, sometimes an asshole. Most have their hearts in the right place. DK's tend to be oblivious to those who they effect and what goes on around them and can take things for granted, but try really hard to do the right thing and be sweetheart. Judaism is a common trait among them.
