Reverse ferret

Used a couple of times in the latest 'Private Eye'. I think 'Obsolete' used it on his blog recently. According to the wikipedia article it was coined by the execrable Kelvin MacKenzie, so it must have been around since he was the vile editor of a vile racist scandal sheet.
I found out not long ago that this MacKenzie is not a real MacKenzie, his grandfather having found it politic to change his surname after having been tried for murder.
Having MacKenzie ancestry myself I was pleased to learn that.
