The word Doxy is still used in Staffordshire. It is (often) being used by a friend to refer to the woman her husband ran off with. So I don't think she has the fluffy bunnies image in mind !

Kevin, I'm not sure if you were serious about the connection with 'ducky', (or if this is relevant), but the affectionate term of 'duck', as in "Are you going up Hanley, duck" is likewise in common use in N.Staffs/the potteries.

.... I never knew 'tart' came from 'sweetheart'.
