That was the chain of sounds I heard the other day.
Playing senior softball (for those 50 years and older), we had a bit of a situation. My good friend Marvin was pitching. Another good friend, Al, was at the plate.
The cracking sound was the ball coming off Al's bat.
The thwocking sound was said ball hitting Marvin squarely in the coconut.
The thudding sound was Marvin hitting the ground.
