Telling Prase: trauma troll

Medical professionals often use code to refer to their patients when speaking to one another. I recently learned one of these codes when speaking to a student who has been shadowing an ER doctor on his rounds. During those rotations, the doctor referred to several "trauma trolls." The student learned that a "trauma troll" is a patient who frequents the ER due to self-inflicted wounds. "Cutters" are one sub-group of the "trauma troll" category.

Using the term "troll" in reference to patients implies a badness, due to the the evil connotation of the monster. This suggests that doctors dislike, or are perhaps repulsed by, such patients.

I wonder if the term drama troll pre-dates the trauma troll, and if it is the young generation of blogging doctors that have coined the term.
