Hydroerotic Asphyxiation

Hydroerotic Asphyxiation - is a form of auto erotica asphyxiation. The subject places their head in a public restroom toilet while masterbating to deprive the subject of oxygen hightening the excitement and pleasure of the masterbater's experience.

A man was found half naked and unconscious in a stall of the JC Pennies men's room covered in water and semen with a subtle smile on his face. An obvious victim of Hydroerotic Asphyxiation.

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.

Hydrosex

When 2 people go into a body of water (such as a pool, a lake, the ocean, etc.) and submerge below the water, holding their breath, then have intercourse until they both finish and complete their session. No pop-ups for air allowed, otherwise the act is no longer valid.

“Bro last night me and Rebecca had hydrosex! We didn’t come up for air until we finished dude!”
