(v.) The act of throwing one's excrement out the window (especially when experiencing plumbing issues in another's home that may lead to greater embarrassment than the act of defenescating itself).

The act of bodily thowing a person out of a window. Defenestration is best executed from a third story (glass) window as it breaks bones but allows the defenestree to limp away.

"I was told not to shoot the king's messenger, so I defenestrated him; he broke both legs. I do believe the king got the message."

Someone who has a really strong opinion about something, believing that their opinion is the only right one.
The most common type of defener listens to nothing but classic rock, thinking modern music is the worst thing to happen to the world since the Holocaust. Defeners will often say that they feel like they were born in the wrong generation.
