Derby is one that drifts over this way, which is 'duck' 'meduck' for both sexes, which my uncle uses a lot even though he's born here, and it nearly got him started on one night when he went in a pub and said have ya got change for the phone me duck. she told her regulars that he'd called her a duck, and they were ready to pounce. He came back from the phone and said thanks me duck. dunno what happened but it must have got sorted, I think his girl friend over heard and explained just in time.
