Usage examples of "cherrystones".

She had looked as dead as Mary and poor old Dave, but he had leaped over her like Jack over the candlestick, his ear screaming from the near miss and his balls drawn up and as hard as a couple of cherrystones, not a state in which a man could make a reasonable diagnosis.
