Why Is The Water Boiling?
Based on what one respected geek said, when a fluid flows through an opening very fast enough, the pressure within the fluid drops drastically due to Bernoulli's principle. Water always "wants" to boil, but is held together by air pressure. Without enough pressure, bubbles of steam will begin to form in the water.

This phenomenon described in the question is Cavitation.
Cavitation is the process of changing the phase from liquid to vapor by reducing pressure, instead of supplying heat. Cavitation is similar to boiling, but takes place by reducing pressure instead of supplying heat.
Let us briefly see what the other terms mean.
Suction is when a fluid is displaced by creating a difference in pressures. This concept is used in vacuum cleaners, which suck in dirt and liquid by creating regions of low pressure.
When an object is compressed in one direction, it expands in the other two directions. This is known as Poisson's phenomenon.
