Wrong Thing

Wrong Thing
 n.

   A design, action, or decision that is clearly incorrect or
   inappropriate. Often capitalized; always emphasized in speech as if
   capitalized. The opposite of the {Right Thing}; more generally,
   anything that is not the Right Thing. In cases where `the good is the
   enemy of the best', the merely good -- although good -- is
   nevertheless the Wrong Thing. "In C, the default is for module-level
   declarations to be visible everywhere, rather than just within the
   module. This is clearly the Wrong Thing."
