Band 5 bullshitter is a term first told to me by someone else who also had treatment at Harefield Hospital. It is used to describe a nurse that tells lies.
Bullshit is fairly self explanatory worldwide but some for non UK visitors, please allow me to explain the band 5 bit. Band 5 is the most common pay grade for nurses in the UK.
I personally now use the phrase for any member of NHS staff that tells lies whether or not they are a doctor, nurse, toilet cleaner or the chief executive.
Anyway less of the explanation and more of the celebration. I have managed to get this phrase into the hallowed Urban Dictionary and you can see more here.
This phrase though now applying to the whole of the NHS organisation will always have its roots at Harefield Hospital in Middlesex which is now part of the Guy’s and St Thomas’ NHS Trust.
