1) A person, hired and paid for, who no matter how high their level of education and/or
experience, will always manage to make matters worse, rather than better. Messing up your neat stack of TPS reports; tripping and spoiling hot coffee on the exec that was about to inform you of your promotion; rear-ending your Porsche with a Honda Civic on a weekly basis.
2) Another
definition of course is: complete absence of tolerance for anything whatsoever. This affliction only lasts to your demise, which should by all rights be imminent.
