Literal meaning: Not A Dud
NAD: (1) NADs are the opposite of DUDs. NADs don't like DUDs (Duds), don't hang out with DUDs, and definitely don't want to be DUDs. NADs do what they want, have fun, party hard, and believe that we are all only young once--so live it up now!
Kate: Are you going out tonight?
Alex: No, I am going to stay home by myself and hang out with my cat while you go out with our friends to a bar have fun.
Katie: I thought you were a NAD?
Alex: I guess I am a DUD.
