Looking at Mer's blog, I found this:

Word o' the blog: Parzival: An epic poem written by Wolfram von Eschenbach. -Reader's Digest Great Encyclopedic Dictionary

So of course I'm thinking "Hmm, sounds like Percival or Parsifal of King Arthur." And sure enough, the first thing that comes up on google is this site: http://www.newadvent.org/cathen/15683a.htm

Basically, in the 13th century this German fellow dictated an epic poem telling of Parzival: "It is the well-[known] story of the simpleton who passes through struggle and temptation and in the end wins the highest earthly happiness and becomes King of the Holy Grail"... Of course, he stole this from the French. Memories of Eng. 316 & Chretien de Troyes! So, I salute you, Merrers, on a good word of the day.

As a funny sidenote, Dale actually said this today when she was about to go back to her room:
"Ok, I'm going to go soak my crotch now."
