How a fake word from The Simpsons ended up in a perfectly cromulent string theory paper: Sciam Observations

How a fake word from The Simpsons ended up in a perfectly cromulent string theory paper: Sciam Observations: "'The Simpsons,' a source of knowledge for all serious theoretical physicists."

"Jebediah: [on film] A noble spirit embiggens the smallest man.
Edna: Embiggens? I never heard that word before I moved to Springfield
Ms. Hoover: I don't know why. It's a perfectly cromulent word.

Here is the word in a rather different context:

While in both cases for P anti-D3-branes the probe approximation is clearly not good, in the set up of this paper we could argue that there is a competing effect which can overcome the desire of the anti-D3s to embiggen, namely their attraction towards the wrapped D5s. Hence, also on the gravity side, the non-supersymmetric states would naively be meta-stable."

"Have any of your colleagues recognized your use of the word?
When I gave a draft of one of the papers using this word to [fellow Simpsons fan] Joe Polchinski [of the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara] and asked him to among other things to comment on the referencing in the paper, he replied "Your referencing looks perfectly cromulent." I didn't remember cromulent and had to look it up myself!"
