The Bald Heretic – Short, bald dude with a goofy beard

From this Wikipedia article:

The Simpsons, an animated series, has used and coined many neologism for humorous effect. The most famous example is Homer Simpson’s signature annoyed grunt, “D’oh!” which has been listed in the Oxford English Dictionary, in addition to smaller references such as OUP’s single-volume Oxford Dictionary of English (second edition).

Few of the following would qualify as neologisms from a strict lexicological perspective due to their extremely limited use outside of the show. For those that have found their way into regular use, the route passes through the considerable fan-base where use of these words carries the prestige of pop-cultural literacy among those who catch the references, just as among other cultural groups a clever parallel to a well-known phrase from the literary or rhetorical canon would be acknowledged.

The following, then, is presented more as a glossary of references than a list of neologisms. This list, however, is distinguished from other Simpsons-related lists by focusing on invented words and phrases rather than the names of specific characters or locations that are well documented elsewhere.

Many of these are intentional mutations, mispronunciations, amplifications, or portmanteaus of recognizable words that reveal or emphasize aspects of the characters using them. Homer, for example, often mispronounces words, showing his ignorance. Grandpa Simpson and Mr. Burns use obsolete or old-sounding words, which emphasize their age. And Professor Frink and Dr. Nick Riviera invent new scientific-sounding jargon to lend meager credibility to their obvious ineptitude.
