My Corporations professor, an adjunct - he's an Antitrust partner at a firm - was recently offered a permanent position to teach the course. Last week he admitted he was horrified to learn that we law students refer to the class as "Corps."
"I know this class isn't as exciting as some others, but really guys - we have come up with something better than that!"
The amusing part to me was that he didn't know we called it that! I've known it as "Corps" from my first year, and I assume the reference is passed down every year. (Other examples: Civ Pro for Civil Procedure, Crim for Criminal Law.) As weird as it may sound, I don't actually think there are negative connotations.
I mean really, how else are you gonna abbreviate it?
