New Word

A moment ago I just sat in my microeconomics lesson listening to explanations of Game Theory when the professor flipped to the next slide with a version of the prisoner's dilema on it.
He tried to explain it using a hard working person and a shirk. I suppose that nobody really knew what a shirk was (this is an economics class, remember) but everyone did understand the meaning of it in some way.
I think shirk is a very beautiful word for a lazy person.
The Longam Dictionary defines it as follows: to deliberately avoid doing something you should do, because you are lazy.

There is the verb to shirk but also the noun a shirker.

Well this is it for today I suppose...
