I’ve heard doctors say things like “he’s crazy!” and “Lord, he stunk like a dead monkey!” and worse.
But I’ve never overheard a nurse say anything nasty, and neither of the nurses I know say bad things about anyone. Perhaps nurses are more cautious withoutsiders. (I’ve never worked directly with nurses.)
I’ve heard the following:
Recto-cranial inversion (having one’s ass where one’s brain should be)
Arthropoidal invasion of the lower alimentary canal (having a bug up one’s butt)
BFK - (booger-faced kid), tactfully stated as EMS (excessive mucal secretions)
With paramedics around here, “Moritz-3” is the radio code for a drunk person.
But they sometimes get 300s and 3000s, too.
As an EMT we had “frequent flyers” but that’s about all I can think of.
