How it's used
Beyond the literal meaning of diving into a pool, this term is widely used metaphorically to describe a sudden and sharp decline in values, such as stock prices, sales figures, or even a person's health. It carries a sense of speed and lack of control, similar to how a diver plunges headfirst into water. When used in sports, it can also imply a deliberate, sometimes exaggerated, fall to deceive a referee, similar to flopping in basketball or soccer.

Do not confuse this with the English loanword 潛水, which means to go underwater or to go silent/inactive in online chat groups. While both involve water, 插水 implies a rapid, downward motion, whereas 潛水 implies staying submerged or hiding.
