nesh means you're feeling a chill. its very common in Derbyshire. mind you its bloody cold in the Pennines.

In the song Sullivan's John, my bother James/ got a rap of the hames.

I asked Paddy Reilly about what it meant. He said it means James got bashed on the head by the harness. He added, it means the end of the argument.

I suppose in the way you refer to it Jim, it refers to the harness getting ravelled and in a mess, perhaps?
