If you aren't using Embiggen in your everyday jibber-jabber, your life must be sad and small. The Simpsons have been around for a couple decades now, and have given us so many fabulous words and made-up Simpsons sayings and Bart slang... SO many that, really, should be in the dictionary despite their dubious meanings. I mean, if you can't figure out what Tramampoline means... come ON. There's a more complete list out there somewhere, I'm sure, but these are the best of the fakes... the best words that the Simpsons have given us.
