If a bowler bowls a ball which does not pitch (hit the ground) before it reaches the batsman, it is known as a full toss. If a full toss reaches the batsman at waist height it is a no-ball. When a fast bowler bowls a full toss which reaches the batsman at waist high or above, it is called a "beamer", which is both a no-ball, a cause for a warning from the umpire, and very much frowned upon if in any way deliberate. You don't get many deliberate beamers in cricket, they're usually the result of a misfire on the bowler's part.
Full tosses are usually dispatched to any part of the park the batsman wishes, although in club cricket the full toss is a deadly delivery. The batsman's eyes light up as he throws the bat at it, quite often resulting in him spooning a catch or missing it completely and being bowled. I took many of my club cricket wickets with full tosses.
