Stumped by a stone-skipping sound? Find the answer here!

The answer to the crossword question “Undesirable sound at a stone-skipping contest is PLOP” is the onomatopoeic word “PLOP“. This word describes the sound that a stone makes when it hits the water during a stone-skipping contest. While this sound is desirable during the first few skips of a stone, as it indicates that the stone is bouncing off the water’s surface, it becomes undesirable when the stone finally sinks into the water. The word “PLOP” represents the sudden and complete end to the stone’s momentum, and signals the end of a competitor’s turn in the contest.
