It reminds me of the words "cromulent"[2] and "embiggen"[3]; coined by The Simpsons but used in everything from BBC articles to scientific research.

popularized by the simpsons, at least cromulent was a valid english word before the episode, I don't think embiggen was.
From Wiktionary: "A humorous, intentionally morphologically opaque neologism coined by American television writer David X. Cohen for 'Lisa the Iconoclast', a 1996 episode of the animated sitcom The Simpsons."
From Merriam-Webster: "It is safe to say that The Simpsons has contributed a great deal to the English language. One famous example is cromulent, which was coined specifically for the 1996 episode 'Lisa the Iconoclast'."
