Sometimes I think my entire vocabulary can be traced back to Seinfeld or The Simpsons. The latter has actually created and/or popularized a few dozen words (see Supernintendo Chalmers, right) several of which have crossed over into the mainstream.
Who could forget words such as:
-- Meh: An interjection expressing apathy, general indifference, and boredom.
-- Saxomophone: Homer's word for Lisa's favorite instrument. (During Lisa's absence, Homer attempted to "play" Lisa's baritone sax by singing into it the words "Saxomophone" to the tune of Beethoven's Fifth Symphony)
-- Yoink!: A verbal exclamation made by a character when stealing an object from its owner or rightful place.
There are also some excellent Simpsons "snowclones," which are adaptable cliched phrases such as "Mmmmmm.... (fill in the blank)," "Worst ______ ever," and "I, for one, welcome our new _____ overlords."
Some Simpsons phrases may sadly and undeservedly be destined for obscurity, such as BBBQ: "Come to Homer's BBBQ. The extra B is for BYOBB." When Bart asks what the extra 'B' is for in BYOBB, Homer replies that it's a typo.
As a bonus, today's lexigraphic term of the day is Portmanteau: a word that is formed by combining both sounds and meanings from two or more words. You may remember it from such words as Craptacular and Sacrilicious.
