Made-up words in The Simpsons – Wikipedia, the free encyclopedia:
Several memes, words and phrases (often neologisms) that started on The Simpsons television series have now become mainstream words or sayings. The most famous of which is Homer’s saying: “D’oh!”, which is referred to in scripts, as well as several episode names, as “annoyed grunt”. D’oh is now listed in the Oxford English Dictionary and even in smaller ones such as OUP’s one volume Oxford Dictionary of English (second edition).
