Get the cockle over mug.
When you are walking and your ankle painfully moves to an uncomfortable angle, this happens when you come off e.g a curb or step. This is a Hull word which is used nowhere else in the world.
Person 1: "Hey, why are you limping?"
Person 2:" Well I just cockled over as I came off that curb over there."
