The term is coined from an old English expression and is used to describe someone who is homosexual.
It comes from the 1930's when shopkeepers had to pay the tax man at the front door of their shops when receiving stock to sell, whereas the "crafty butcher" would have his MEAT delivered to the BACK DOOR.
"Check that guy, he's a crafty butcher, look at the way he walks."
"What do you mean?"
"Well he obviously takes meat round his back door."
A male homosexual - one who likes to take his meat around the back.
"A fayre visaged manne was in the partee,
Lipsed of voyse, and limpe of wriste eek.
Ful wynsomme a crafty butcher was he,
We played heide thee sausage and I could not sitte downe for a weeke."
- Geoffrey Chaucer, Prologue to the Canterbury Tales
A Homosexual, Mostly refering to Male homosexuality;
One who likes to have his meat taken around the back
Where would you like this meat put?
Round the back please, that's where I like it best
Oh I see you're a Crafty Butcher, can you open up then, I can't get in
angling the meat towards the back chute
I can't take credit for this one I read it in an English comic book Raz or something but I thought I should share.
