While chasing a rabbit today (don’t ask), I ended up at Bierce’s
Devil Dictionary, and the definition for abattoir has this:
A place where cattle slaughter kine. It is commonly placed at some distance from the haunts of our species, in order that they who devour the flesh may not be hocked by the sight of the blood.
This is supported by the scan (this is from the one on the Wiki entry; the IA version linked to in our production is pretty blurry):
I can find no definition of “hocked,” in M-W or my (small) IOS OED or in a wider internet search, that would fit that sentence. Unless David can find one in the big OED, surely this should be “shocked”; what does anyone else think?
