Dud is the opposite of funster. You can easily ascertain whether someone is fun-loving, maybe a little crazy OR are they the type of person to be, well, a dud. You will find a dud working overtime at his or her cube, whilst the funster is already at happy hour.
Karen to John O who she's never met: "So, John: are you a funster or a dud?"
John O. "Well I guess you'll have to be the judge of that after we meet" - clearly a dud.

Karen: "Okay, I'll hang with Troy, he's the ultimate funster!"
