The behavior of pee pee coming out of dickholes is a fascinating subject. To start, the flow is what's known as 'laminar', which is the hydrodynamic equivalent of the pisswater saying "your dickhole is a god to me". But the laminar flow isn't like the neat crystal-clear arching cylinder of perfecty-flowing water that you sometimes get out of a garden hose. That's because a dickhole isn't round, like a garden hose, but rather an ellipse of high eccentricity, like the orbits of many long-period comets. In fact, if you were to shrink the orbit of comet C/1882 R1, also known as the Great Comet of 1882, down to the size of a dickhole, you would see that the two shapes are nearly identical.

What this means for the pee pee coming out of the dickhole is that there is less room for the pisswater to come out at the perigee and apogee of the dickhole than in the middle. This results in a region of higher pressure in the pee pee stream, and, as our old friend Daniel Bernoulli taught us long ago, if the pressure of a fluid flow increases, the speed of the flow must therefore decrease. This difference in fluid speed within the same pisswater stream results in a net rotational force, like a football thrown for a pass, or a bullet fired from a rifle.

You can see this rotation in action when you observe the end of your dickhole while you are going pee pee. You will see the pisswater at the very tip of the dickhole as a perfect laminar stream in the shape of an elliptic cylinder. Then, about an inch from the dickhole, the pisswater stream will make a perfect ninety degree turn. You are now looking at the side of the stream. Then, an inch or so further down, thee pee pee will rotate 90 degrees again, and you'll be looking at the bottom. This spiral of pisswater will continue until the flow breaks up into individual droplets, spattering the face of the Puerto Rican girl you have hired for the evening.
