At Wikipedia, a list of made-up words in the Simpsons, including “craptacular“, “cromulent“, “embiggen” (from the Springfield town motto, “A noble spirit embiggens the smallest man”) , “tomacco“:

A tomacco is originally a fictional hybrid fruit that is half tomato and half tobacco, from the 1999 episode “E-I-E-I-(Annoyed Grunt)” of The Simpsons; the method used to create the tomacco in the episode is fictional. The tomacco became real when it was allegedly produced in 2003. The tomacco is one of the few made-up words in The Simpsons that resulted in real life application.

and not forgetting “I, for one, welcome our new insect overlords“.
