- wacko! -

The English language is so perverse.
Sometimes it conjures a 'WOW! I've always wanted to know what that thingamajig was called!'
And sometimes, it's a 'Is it really necessary for that word to exist?' kinda deal.

Defenestration means 'to throw someone or something out of a window.'
n. [mythically from a traditional Czech assasination method]
[but apparently not a myth, just became illegal]

Other meanings:
1. Proper karmic retribution for an incorrigible punster. "Oh, god, that was awful!" "Quick! Defenestrate him!"

2. The act of exiting a windows system in order to get better response time from a full-screen program.

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. The act of completely removing Microsoft Windows from a
PC in favor of a better OS (typically Linux).

I find meaning number 5 very evolved indeed.
