Cow corner
the area of the field (roughly) between deep mid-wicket and wide long-on. So called because it is where cow shots are aimed.
Cow shot
a hard shot, usually in the air, across the line of a full-pitched ball, aiming to hit the ball over the boundary at cow corner, with very little regard to proper technique. Very powerful and a good way of hitting boundary sixes, but must be timed perfectly to avoid being bowled, or either skying the ball or getting a leading edge and so being caught. A type of slog.
