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!"
