np- - Jargon File (4.4.4, 14 Aug 2003) :

  NP-
   /N.P/, pref.
  
     Extremely. Used to modify adjectives describing a level or quality of
     difficulty; the connotation is often `more so than it should be'.
  This
     is generalized from the computer-science terms NP-hard and
     NP-complete; NP-complete problems all seem to be very hard, but so
  far
     no one has found a proof that they are. NP is the set of
     Nondeterministic-Polynomial problems, those that can be completed by
  a
     nondeterministic Turing machine in an amount of time that is a
     polynomial function of the size of the input; a solution for one
     NP-complete problem would solve all the others. "Coding a BitBlt
     implementation to perform correctly in every case is NP-annoying."
  
     Note, however, that strictly speaking this usage is misleading; there
     are plenty of easy problems in class NP. NP-complete problems are
  hard
     not because they are in class NP, but because they are the hardest
     problems in class NP.
