hacked up
 adj.

   Sufficiently patched, kluged, and tweaked that the surgical scars are
   beginning to crowd out normal tissue (compare {critical mass}). Not

   done with some eye to coherence and continued maintainability, the
   software may emerge better for the experience. Contrast {hack up}.
