duration 

that means length of time

I suck at call duration.

Duration Queen 

Woman (or gay man) who prefers men who have more stamina in bed, often not being satisfied until an hour or more of sex has been had, and frequently chastising men who do not live up to their expectations.

"That whore is just a duration queen. I was inside of her for 25 minutes and she wasn't satisfied. She had to get her dog to finish her off."

hug-duration calculator 

Refers to the mathematical-analysis procedure that you use to determine how long it's been since two embracing people have seen each other, how fond they are of each other, how long they've known each other, etc.

The hug-duration calculator can be very useful in guessing the details of two people's overall feelings about each other. For example, if they rush headlong towards each other "at first sighting" and totally bear-hug da crap outta each other (extra points if da guy sweeps da gal up off her feet and happily whirls her around a couple of times), this indicates that they have been apart for many months or even a year or more, and so they are simply overjoyed to finally be reunited. But if they simply step swiftly forward and enfold each other in a "deeply-tight" and super-long embrace (such as a minute or more; extra points if they also tear-dampen each other's shoulders and/or treat each other to shoulder-blade scrunchiez during said extended squeeze), this indicates that they are simply extra-fond of each other, and/or they are super-grateful for each other's friendship, emotional support, and occasional kindly assistance.

Long-Duration Motion Machines

Long-Duration Motion Machines are hypothetical devices designed to operate for extremely long periods without external energy input, while still respecting known conservation laws and thermodynamics. Unlike perpetual motion machines, they do not claim infinite operation or energy creation. Instead, they rely on ultra-slow energy dissipation, delayed equilibration, environmental energy harvesting, or probabilistic and extraphysical mechanisms. The key distinction is that long-duration machines eventually stop, while perpetual motion machines violate physical laws by claiming endless motion or energy output. These machines are often discussed in theoretical engineering, speculative physics, and borderline scientific proposals.

Long-Duration Motion Machines — Example

A hypothetical machine uses ultra-low-friction components, cosmic background radiation harvesting, and delayed thermal equilibration to keep moving for millions of years. It never produces excess energy and slowly loses motion over astronomical timescales. Unlike a perpetual motion machine, it obeys thermodynamics but exploits environmental and probabilistic factors to extend operation far beyond conventional machines.

Long-Duration Motion Machines

The natural and artificial systems that move things across geological timescales—glaciers that carve valleys over millennia, tectonic plates that rearrange continents over eons, and human institutions that change so slowly they might as well be geological. Long-duration motion machines include the slowly shifting course of rivers, the gradual uplift of mountains, and the federal government, which moves with approximately the same speed and predictability as a continent, just with more paperwork.

Example: "She studied glaciers as long-duration motion machines, watching them inch forward year after year, carving landscapes with patience that humans cannot fathom. When her grant was delayed by government bureaucracy—another long-duration motion machine—she found the irony unbearable. The glacier, she noted, was faster."

Short-Duration Motion

Movement that happens so quickly you barely register it, from the blink of an eye to the snap of a finger to the moment your phone slides off the table and you fail to catch it. Short-duration motion is the realm of reflexes, instinct, and regret—the split second when you realize you've said something stupid and watch the other person's face change in slow motion, even though the actual motion was fast. It's the temporal home of accidents, epiphanies, and the exact moment a toast lands butter-side down.

Example: "The short-duration motion of the car accident lasted less than a second, but he replayed it for months—the screech, the impact, the airbag. His therapist said that's normal: short events, long consequences. He said he'd prefer shorter consequences and longer events, like a nice vacation."
