I’ve asked several members of the medical community what they mean on ER when they say someone had an “LOL” & cannot get an answer. Obviously “LOC” is a loss of consciousness. Can anyone clarify? I suspect they’re just making things up.
I’d get suspicious if they also refer to someone having a “ROFL” or a “STFU”. Could be script kiddies.

Loss of Life?
IANAMD and i’ve never seen ER, but a WAG:
loss of lucidness ?

I think Quitesane probably had it nailed (I might prefer the more pedandic-sounding “lucidity”), although,

I am also not a healthcare workerm nor do I watch ER, and,

This really should have gone into Cafe Society, IMHO.
Lucidity ofcourse. English is my second language and Mirriam Websters mentioned “lucidness” but not “lucidity”. “Lucidity” was the word i was looking for though.
Can’t be loss of life, as it’s used to describe some poor slob being wheeled in for treatment. Loss of lucidity makes sense, perhaps that’s it. But now you guys have got me more confused than ever -
What’s having a “ROFL” or a “STFU”.
What’s IANAMD & a WAG?
And what do you mean by “3. This really should have gone into Cafe Society, IMHO.” I thought this was Cafe Society? Are you saying you’re a ho?
I thought I was doing pretty good w/this SDMB when I figured out how to use the spoiler box, but now it appears I’m in way over my head. Has someone posted an acronym buster somewhere?
ROTF: Rolling On The Floor (laughing)
STFU: Shut The Fuck Up
IANAMD: I Am Not A Medical Doctor (It’s usually just IANAD, but perhaps Quitesane is some kind of non-MD doctor.)
WAG: Wild-Assed Guess
It’s in Cafe Society now, but it was probably started in General Questions or some other forum, and then got moved by a moderator. That kind of thing does look a bit funny.
ROFL = rolling on the floor laughing
STFU = Shut the f*** up
IANA = I am not a(n), MD = medical doctor
WAG = wild ass guess
Wow, thanks for the replies - I half thought I’d just get flamed. Or else that the acronyms weren’t a shared language and were just, ya know, PFMA. tee-hee.
(Pulled From Mid-Air is the polite version)
Loss of Lunch? 
Loss Of Lucidity? Come on, we can do better than that.
Loss Of Lipids.
Lots Of Lysosomes
Lump On Liver
Luscious Old Labia (don’t ask)
Large Ornery Leukocytes
Take your pick.
It’s not refering to a medical condition at all. It’s refering to the patient:
LOL: Little Old Lady
Lords of Lycra.
now opening for Lots of Lysosomes
Bingo! We have a winner!
Yes, LOL is paramedic shorthand for Loss Of Life, as in, “We have an MVA (motor vehicle accident), with LOL”.
No, I’m saying I’m an idiot who keeps three browser windows open on SDMB (Straight Dope Message Board, for the acronym-challenged); one each for the BBQ Pit, Cafe Society, and General Questions, and in my idiocy, I thought I was reading a question from General Questions.
Sorry about that.
mung has it nailed. An LOL is a Little Old Lady.
An LOLNAD is a Little Old Lady in No Apparent Distress.
By the way, it is not uncommon to find the notation FOS on medical charts, followed by a prescription for a laxitive…
I thought it stood for Lump of Love.
