I love doing the nuclear sub while in the bath

Sub-Nuclear Engineering

Going deeper into the heart of matter than anyone should: engineering with quarks, gluons, leptons, and bosons. This is the manipulation of the fundamental quantum fields themselves. The goal might be to create stable "strange matter" (made of up, down, and strange quarks), generate focused beams of gluons for "strong force welding," or stabilize the Higgs field in a local area to give particles variable mass. It's the engineering of the universe's source code, long before it compiles into recognizable atoms.
Example: "Their weapon wasn't a laser; it was a sub-nuclear engineering projector. It fired a coherent beam of disentangled gluons that briefly severed the strong nuclear force in its path, causing any matter it touched to explosively disintegrate into a cloud of free quarks."

Sub-Nuclear Harnessing

Extracting energy or applying force via the violent, confining interactions inside the nucleus, specifically the realm of quarks and gluons governed by Quantum Chromodynamics (QCD). This could involve tapping the energy released in quark rearrangements, harnessing the Casimir-like effect of the vacuum within nucleons, or using the color charge of quarks for a form of energy storage or transmission unimaginable in electromagnetism. It's power from the furnace where mass itself is forged.
Example: "The theoretical 'QCD Battery' works on sub-nuclear harnessing. It stores energy by putting quarks inside nucleons into excited, high-energy color states. Releasing that energy gives you a flash of pure strong force, capable of vaporizing mountains, all from a battery the size of a grape."

Nuclear Submarine 

While wearing a Condom for your safety, you dip your cock in Tabasco sauce then jam it in a woman’s ass. The burning sensation that was caused by your submarine would be as if a nuclear bomb went off in her ass!!!
She screamed in pain when I gave her the Nuclear Submarine!

nuclear submarine 

When defecating, the biggest, most awesomely large dump that you haven't had in a good long time. Usually arises from not crapping for more than 48 hours or when coming off of constipation. Called so because the waste is so big, it's like a nuclear submarine trying to leave the bowels, which is a very large submarine. An atomic dump.
Today I went over Memere's house and launched a nuclear submarine.

Try as he might, the nuclear submarine deep in Gorby's colon wouldn't come free, until he had some Taco Bell and it was launched in the public restroom.

The number of years you are still sexually active
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
You didn't get any napkins with your takeout pork fried rice? Womp womp.
