I'm a complete sucker for jargon. Specialized vocabulary identifies you a an insider and, whether you mean it to or not, it reveals a lot about your group.
This collection of Medical Slang is brash, irreverent, and profane. It may strike some folks as callous, but, having worked in hospitals, I know you have to develop a pretty black sense of humor to keep from being overwhelmed.
My favorite? Hard to pick, but it might be: "Dagenham - (psychiatry) or "Three Stops Beyond Barking": severely disturbed/mad (based on British train station names)"
OTOH, there's something almost gleefully macabre about: "DRTTTT - Dead Right There, There, There and There (patient dead and in multiple parts at scene of accident)"
