The medical world is full of acronyms. A patient who is “DNR” has a directive demanding that doctors not use certain means to potentially prolong the patient’s life. “CBC” stands for “complete blood count,” a diagnostic tool used to measure various aspects of the components of a patient’s blood. And there’s “NPO,” which stands for “nil per os” — Latin for “nothing by mouth” — and instructs patients and caretakers alike that the patient must refrain from eating or drinking until further notice.

And then, there’s “TTFO” — “told to [go away],” let’s say.

In 2003, the BBC interviewed Dr. Adam Fox, a physician at St. Mary’s Hospital in London. Fox had “spent four years charting over 200 colorful examples” of doctor slang — terms physicians have used to, among themselves, complain about patients out in the open. One just needed to know the lingo. Among the offensive-if-you-knew-what-it-meant initialisms were FLK (“funny-looking kid”), LOBNH (“lights on but nobody’s home”), and DBI (“dirt bag index,” referencing the numbers of missing teeth and tattoos of the patient in question). Another one, according to Wikipedia (and not mentioned in the profile of Fox) is GOMER, an acronym for “get out of my emergency room,” which is used to describe a patient “bordering on death, hence taking up room unnecessarily in the hospital.” (Yikes.)

In general, these notes go undiscovered or, at least, unnoticed by patients, which is a good thing, because no one — least of all an ailing person awaiting care in a hospital — wants to be find out that he or she is a ten out of ten on the dirt bag index or so sickly as to not warrant the attention of an ER doc. But in one case documented by Dr. Fox, a patient did, in fact, notice an initialism — the aforementioned TTFO. Thankfully, the doctor covered for himself — he said it stood for “to take fluids orally.”

Bonus fact: Doctors aren’t the only ones who use snarky acronyms and initialisms to describe those who they are charged with helping, but are often considered less-than-desirable. Computer user support professionals (the IT help desk at your job, perhaps) have one as well: PEBCAK. It means “user error,” but of course, is in code: it stands for “Problem Exists Between Chair and Keyboard.” It’s so commonly used that it once made an appearance as a Daily Double on Jeopardy! in the category “Online Insults,” as seen here.
