I've no idea what you are talking about. I presume it is about football. I had to look up
John Stones, but assume the answer is nothing to do with him or football. If it is I'm in trouble. I assume the definition is unsettled, but perhaps someone can put me right if I've got it wrong. My left hand side is very empty, so I need to go away and work on some more. I keep falling asleep in the sun.
