One should always use the word that conveys ones meaning in the cleanest, most concise way possible. The written word is a terrible substitute for face-to-face communication as it is; getting all "whatevs yo" about it only leads to confusion.

We're now five comments deep on whether or not the word is appropriate. QED, it's not. But just to prove a point:

- rationalwiki is the only site I can find on the Internet that refers to "a poe" which, paradoxically, uses the statement "'Poe' as a noun has become almost as ubiquitous as Poe's Law itself."

- Urbandictionary has seven definitions of "poe", none of which match the usage here. In fact, Urbandictionary asserts that "a poe" is the author of said parody, not the parody itself.

- Poe's Law is easy to invoke without confusion.

There are times when inventing new words is beneficial to the language. Then there are times when attempting to shoehorn a definition just adds confusion. We all know what satire is. We all know what Poe's Law is. We don't, however, agree on what "a Poe" is so perhaps it's not the best word to use.

That's all I'm saying.
