defenestration

   [mythically  from a traditional Bohemian assassination method, via SF
   fandom]

   1.  Proper karmic retribution for an incorrigible punster. "Oh, ghod,
   that was awful!" "Quick! Defenestrate him!"

   2.  The  act  of  completely  removing Micro$oft Windows from a PC in
   favor of a better OS (typically Linux).

   3.  The act of discarding something under the assumption that it will
   improve matters. "I don't have any disk space left." "Well, why don't
   you defenestrate that 100 megs worth of old core dumps?"

   4.  Under  a GUI, the act of dragging something out of a window (onto
   the screen). "Next, defenestrate the MugWump icon."

   5.  [obs.]  The act of exiting a window system in order to get better
   response  time  from  a  full-screen  program.  This  comes  from the
   dictionary meaning of defenestrate, which is to throw something out a
   window.
