evil adj. As used by hackers, implies that some system, program,
   person, or institution is sufficiently maldesigned as to be not worth
   the bother of dealing with. Unlike the adjectives in the
   {cretinous}/{losing}/{brain-damaged} series, `evil' does not imply
   incompetence or bad design, but rather a set of goals or design criteria
   fatally incompatible with the speaker's. This usage is more an esthetic
   and engineering judgment than a moral one in the mainstream sense. "We
   thought about adding a {Blue Glue} interface but decided it was too evil
   to deal with." "{TECO} is neat, but it can be pretty evil if you're
   prone to typos." Often pronounced with the first syllable lengthened, as
   /eeee'vil/. Compare {evil and rude}.
