I'm reading Calvin Trillin's Remembering Denny, which looks back to Yale in the 1950s, among other things. This quote cracked me up:

My boyhood friend from Kansas City who had enrolled at Princeton the same autumn I showed up at Yale had a roommate I never heard him address as anything but Eberhard Faber the Pencil King, as in "Could you please pass the salt, Eberhard Faber the Pencil King?" There were, of course, at Yale as well as Princeton, boarding-school types you wouldn't joke with the way Eddie Williams could joke with Eb Faber--people who seemed to resent the presence of people they didn't recognize from the cotillion. For them, Eddie used a Princeton phrase that I've mentioned ever since when the subject of evocative epithets comes up: tweedy shitballs.
