The severe lack of boing boing only known by gura

Theres a reason im not BOING BOING , it comes down to science , i am hydrodynamic

Hydrodynamic

The act of moving swiftly through water.

A terd that disappears in your toilet is a good example of a hydrodynamic mass.

Hydrodynamicity

How hydrodynamic a thing is.

My balls have more hydrodynamicity than my hair.

Hydrodynamics

The study of fluids (liquids and gases) in motion, and the forces acting upon them. It's the science of flow, pressure, drag, and turbulence, essential for designing everything from submarines and aircraft wings to arterial stents and planetary weather models. In an alien context, it expands to "xenohydrodynamics," modeling how strange fluids—like liquid methane on Titan or supercritical carbon dioxide on Venus—behave under different gravities and temperatures. It answers questions about alien ocean currents, atmospheric circulation, and the design of vehicles meant to navigate non-water seas.

Example: Engineers using Hydrodynamics to design a silent submarine drone for exploring Europa's subsurface ocean must model how its shape interacts with salty water under immense pressure and near-freezing temperatures. An astronomer simulating the hurricane-force methane rivers flowing across Titan's surface is applying hydrodynamic principles to an alien fluid system.
