Porkpetual (motion) 

It's the back and forth motion of a porky rod or a sausage.

Easily mistaken for perpetual (motion).

Dude did you see the sausage rolling yesterday.

Hell yeah dude, that was some serious porkpetual (motion).

perpetual motion 

Continuous movement, not impeded by friction or forces, and travelling at the same speed.

Perpetual motion could be used to provide electrical energy. Should an electromagnetic generator be constructed around Darwin's grave in the year 2006, it would be able to power approximately 25% of the world's electrical consumption by 2008. The machine would work in the following way: Darwin continually spins in his grave due to the presence of mindless idiots in the human race, of which there are a great number (thus increasing Darwin's rotational speed). All you need to do is electrically charge his body and you have an infinite power supply (just as human stupidity is infinite). There have been, and always will be, idiots in the world, as provided by teenaged mothers, thus providing perpetual motion on the part of Darwin's corpse.

Perpetual Motion 

An incredibly tiring drill for the sport of water polo, in which at no time does a player stop moving in the water (hence the name: perpetual motion). Perpetual Motion, though tiring, can be quite fun if there are a large amount of players. However, without enough people, the players tend to be too exhausted to enjoy themselves, even if getting an extreme workout. At first, Perpetual Motion, also called "Perpet." (per-petch), is a confusing drill to learn, with players swimming all around to different parts of the pool and polo balls being thrown at both nets. Once the drill is learned, it is easy enough to follow though.

Person: Hey! Want to hang out?
Water Polo Player: I'm too tired, I'm gonna go sleep. We did perpetual motion for half of polo practice today.

Perpetual motion 

During 69 he suddenly shoves his cock deep down her throat causing her to both gag and vomit on his dick and fart into his face - in response he gags and vomits between her leg.

Eternal motion.... if it's more than a fart.

Hotel housekeeping refused to clean the sheets after the guests performed Perpetual Motion

perpetual motion squad 

The team name from The Big Bang Theory. According to Howard Wolowitz, it is beyond the law of physics and, plus, a little heads for the ladies because they can go all night.

For an awesome team name, we should be the perpetual motion squad or pms for short.

Poopetual motion

Describes the act of poop moving continuously, specifically moving between 2 or more buttholes; when a person poops into another person's butthole, and then that 2nd person poops into the 1st person's butthole, and then the 1st person poops into the 2nd's butt again (effectively re-pooping their own poop for a 2nd time, plus whatever additional poop the 2nd person had pooped) and the cycle repeats; commonly known as "pooping back and forth"

In middle school, my friend Casey & I watched a video on the internet of 2 friends pooping back & forth, inspiring us to pull our own pants down & create some "Poopetual motion" for ourselves.

Loco-Perpetual Motion

The Theory that any perpetual motion that one comes across is always local to ones location

Loco-Perpetual Motion is a serious thought for one's mind.
