Have you heard of tribology?

In my search for any non-professional descriptions of what is tribology I found a blog Word Imperfect. Their motto is 'Have fun with a new word each day. I'll choose a word. You make up a meaning.' Apparently 'tribology' can be quite a riddle for those who try to figure out what it is.
Imagine a world where people hear the word 'tribology' and think of friction, lubrication, etc. instantly. Right....
Enjoy.
