The act of letting people around you know that you are about to shit your pants.
Hey guys, Major soiler alert coming!
n. secret notification, usually from one nurse to another, that a patient has been incontinent of feces or urine; a signal used by care staff who wish to avoid the clean-up or who wish to save the patient's dignity by removing visitors from the room.
This is a funny time for emergency blood work. And what the heck is a serum reiff-trenchel osmolality?
Don't be a dweeb doctor. That was just a soiler alert.
