There have been many entries to this dictionary over the last year, when it was created by me and of a friend of mine. See, we have this tendency to create words that properly express what we're thinking/feeling at any given moment.
decrapitate -- "After Hurricane Katrina, it was necessary to decrapitate New Orleans."
obviosity -- used like "curiosity" as in, "That's an obviosity"
smarticle (courtesy of Estevan) -- "Aren't I smarticle?" or "Hey, did you catch Newsweek? There was a smarticle on technology in education."
