A very dedicated or possibly bored person has compiled a list of words that didn’t exist until they were spoken on The Simpsons. An exhaustive list that is a really funny read. Some of the best that I find myself using all of the time: craptacular, S-M-R-T, speed holes, and privately, drunkening.
Just reading this list makes me realize how good that show is.
Shamlessly stolen from Boing Boing, the Simpsons list on Wikipedia
*** Update – Why the heck didn’t anybody tell me I can’t spell “Simpsons”?
