means A fast-bowled cricket delivery pitched right at the batter's feet or just below the bat, notoriously hard to defend because it arrives too full to drive and too low to pull.

from The origin is genuinely murky — nobody can prove it. The leading theory ties it to Yorkshire, the English county famed for producing relentlessly accurate, miserly bowlers, as if the delivery itself carried a county passport. Another old guess links it to 'to york,' meaning to cheat or trick, since the ball deceives batters by sneaking in low and full when they expect something else. Cricket historians generally shrug and admit no single account is confirmed.
