Unnatural Death - Dorothy L. Sayers

"You are too easily surprised," said Mr Towkington. "Many words have no legal meaning. Others have a legal meaning very unlike their ordinary meaning. For example, the word "daffy-down-dilly". It is a criminal libel to call a lawyer a daffy-down-dilly. Ha! Yes, I advice you never to do such a thing. No, I certainly advise you never to do it. [...]"

 

Anyone else tempted to try this word on a British lawyer? Well, I looked the meaning of it up and it might be best to leave it be.
