Some say that Grutness is a state of mind, but, as I was recently delighted to read in Tim Dee's excellent book The Running Sky, it is also a place:

Imagine my even greater delight when I realised that I have actually been within 600 yards of Grutness. In March 1985, some archaeological colleagues and I paid a very wet visit to the nearby ancient settlement of Jarlshof.
Apparently, the name Grutness is from the Old Scandanavian grjót nes, meaning gravel promontory.
So, there you have it: Gruts means gravels.
What does Grutness mean to you chaps?

Jen just now:
I perceive grutness as a welcome periodic tangential distraction - something to be absorbed rather like the process of osmosis. I don't think I would like it thrust on me, but I guess that due to Jen's proximity to the grutmaster it is something that she finds difficult to avoid. I hope that's clear.
