Keepie-uppie is a British, playful name for keeping a football in the air as long as you can, without letting it hit the ground. You use light kicks with your feet, and often your thighs or head, to tap the ball up again and again. It is a skill and a pastime, not a full match: people do it in the garden, on the street, or as a warm-up. The spelling is informal and a bit cute — you will also see keepy-uppy. Americans more often say keep-ups or just talk about juggling a soccer ball. It is casual talk among football people; you would not put keepie-uppie in a serious report. Doing it well shows control. Doing it badly is still fun, and the ball always wins in the end.
