 Get the nithermug.
Get the nithermug. The condition one finds oneself in after spending an appreciable amount of time in nithering conditions.  The kind of cold where you can't feel your fingers, toes or nose any more, and don't look forward to them coming back, cos it'll hurt.

 Get the nitheredmug.
Get the nitheredmug. Freezing, cold enough to freeze the balls off a brass monkey. Seems to be a Yorkshire term, not surprising, lots of words for cold up there.
