Late getting here so maybe this has been said earlier but a limey is a brit and a mick is an irishman..I am irish.
See post 55.
A lot of Irishmen in Britain get the nickname Mick or Paddy.
If I was called a limey I would not be offended I see that comment in fact as part of our heritage and it also shows that us Brits had an understanding of natural medicine way back.
