wedged adj. 1. To be stuck, incapable of proceeding without help. This
   is different from having crashed. If the system has crashed, it has
   become totally non-functioning. If the system is wedged, it is trying to
   do something but cannot make progress; it may be capable of doing a few
   things, but not be fully operational. For example, a process may become
   wedged if it {deadlock}s with another (but not all instances of wedging
   are deadlocks). See also {gronk}, {locked up}, {hosed}, {hung} (wedged
   is more severe than {hung}). 2. Often refers to humans suffering
   misconceptions. "He's totally wedged -- he's convinced that he can
   levitate through meditation." 3. [Unix] Specifically used to describe
   the state of a TTY left in a losing state by abort of a screen-oriented
   program or one that has messed with the line discipline in some obscure
   way.

   There is some dispute over the origin of this term. It is usually
   thought to derive from a common description of recto-cranial inversion;
   however, it may actually have originated with older `hot-press' printing
   technology in which physical type elements were locked into type frames
   with wedges driven in by mallets. Once this had been done, no changes in
   the typesetting for that page could be made.
