Jabberwocky & The Origin of Vorpal

The poem "Jabberwocky" is read by Alice early in the Lewis Carroll book "Through The Looking Glass", the sequel to "Alice's Adventures in Wonderland". What I find interesting here is that this is the first usage of the word 'vorpal' in the English language - a portmanteau of voracious and corporeal. As gamers - we just know the word to mean "really super badass sharp".

What other words do we commonly think of as "unique" to the RPG gaming community? Which of them are truely unique, or (more likely) actually derived from some other source? Are there any examples of words or phrases that truly have its roots in the RPG community that have moved into the main stream? I can think of a few, but first I want to hear what you have to say. In the meantime, I'll leave you with the Sir John Tenniel illustration of the monster (circa 1871) and original Lewis Carroll "Jabberwocky" poem.

Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.

"Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!"

He took his vorpal sword in hand:
Long time the manxome foe he sought --
So rested he by the Tumtum tree,
And stood awhile in thought

And as in uffish thought he stood,
The Jabberwock, with eyes of flame,
Came whiffling through the tulgey wood,
And burbled as it came!

One, two! One, two! and through and through
The vorpal blade went snicker-snack!
He left it dead, and with its head
He went galumphing back.

"And hast thou slain the Jabberwock?
Come to my arms, my beamish boy!
O frabjous day! Callooh! Callay!"
He chortled in his joy.

'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
