   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."

   response time from a full-screen program. This comes from the
   dictionary meaning of defenestrate, which is to throw something out a
   window.
