The Daphne:  A character in game that is just like Daphne in Scooby Doo:  Always falling into traps, getting kidnapped, should no better than to do stupid shit but does it anyway, fails the majority of her rolls except for some type of saving throw.

I got a call while I was at work from an old friend that was running a game this afternoon.  His sister was playing an old character of mine, but was a total Daphne and he didn't know how to handle it.  I asked if it was just bad dice rolls or bad roleplaying.  He responded that it was both.  For the dice, I suggested freezing them for ten minutes or just go to the secret stash and loan her some Mojo Dice.  For her playing, I suggested use it for some comic relief.
