Large muddy hole

[Moo]

You learn something new here every day. I always thought it was spelled 'nerk'.

 

[thiambal]

nerk - same meaning as idiot or jerk (e.g. "charmless nerk"); used in the BBC comedy Porridge; considered an extremely mild insult for decades.

Ah, good point Moo, you may be right, spelling never was my strong point!

Found the above quote in wikipedia under 'fictional expletives' - glad to say the definition was ery close to my own.
