Yorkshire name, meaning "a calf that's fattened through the Summer, to be slaughtered in the Fall."
A version of "meat calf", it could mean a herdsman, a slaughterer, or someone with a "sleek appearance".
I can just think of a mother, talking about a son with a bit of chub. "Oh, you're just Mummy's little meat calf, you are."
He never thinks about the more sinister parts of this...
