Nargery
Since two of you have asked me tonight what "nargery" means, I thought I would tell you the story. It's a Cambridge word.

Once upon a time at Cambridge (so the story goes), before the days of state-subsidised tuition, there were two kinds of people you might meet. There were the gentlemen, the sons of the gentry and nobility, who were at the university because they could afford to be. They were often not very interested in academic work, preferring to spend their time rowing and hunting and gambling at Newmarket.

There were also the people who were there on scholarships because they loved their subjects, worked hard, and were fanatical about what they did. They would even talk about their subject in fascinated tones outside of lectures and tutorials— even, perhaps, at parties! The gentlemen of leisure looked down on these students, of course: they would call such a person a "narg", because he was Not A Real Gentleman.

So as time went on, people who talked shop outside the times when it was necessary were called nargs, doing so was narging, and the practice of indecently talking about your subject in public is nargery. Along with the great majority of compscis, I am particularly commonly guilty of it.

Does that make sense? firinel points out that it's even in the Jargon File.
