Fluid Mechanics

The one area of physics where its researchers are actually mostly mathematicians.

Ed: Ey Bob I am studying fluid mechanics
Bob: You mean the area of physics you see mathematicians and engineers study instead of physicists?

Mechanicking

(Noun) A sexual act that involves, from beginning to end, the recipient on all fours and then placing their palms flat against the wall facing them or grabbing hold of a bed's headboard while the giving party slides partially underneath them and places recipient's cock in their mouth and begins the much needed stimuli. Then the giver also begins anal simulation with fingers on hand. Throughout the act the giver may slide back or forward alternating the stimulation they are giving using their mouth and tongue on the cock, testicles, and asshole at their own discretion but not leaving any of the parts unstimulated. The action is usually concluded by the woman penetrating asshole with her finger (as if she hasn't already) at the apex of stimulation resulting in the recipient coming hard while inside the giver's mouth whete it is traditionally consumed posthaste.

Nikki appealed to Betsy, "Lover I am in need of a serious tune up, maybe even sn oil change. Do you think maybe tonight you could do some mechanicking on me to try and fix the problem?" Clearly aggravated, Betsy looked down at her phone and saw that one of her dope connections relayed to her not too long ago that if she wanted any of the candy he had for her it was going to cost her the regular going rate of both anal sex and A blow job, in that order, when she snapped, "I don't know, Goddammit, I swear all you ever think about is sex. Everything is not about you and your stupid cock".

mechanic's special 

A vehicle listed as a "mechanic's special" on craigslist appears to be, at first glance, a remarkable deal. A mechanic's special is usually a vehicle listed far below its blue book value, with a few minor issues outlined that any competent backyard mechanic can easily diagnose and fix. This problems are usually referred to only in the vaguest of terms, such as a "clunking sound coming from the transmission" or "hissing sound from the radiator."

Of course, these problems turn out to be much more severe - such as a blown headgasket, thrashed transmission, detonated cylinder, and the like. The odometer reading is often conspicuously absent from the reading. The owner will often feign ignorance about vehicles in hopes of getting rid of it at a good price, but actually are often competent car people themselves.

The only valid use for a mechanic's special is as a parts vehicle, and only then once the owner has been talked down to a reasonable price.

quantum mechanics 

An extremely specialized area of physics that is really hard to understand, but it does actually make sense when you study it. Trust me, it's fucked up and involves a lot of fucked up math which I'm not going to explain but some of the other definitions on here explain it.

It will fuck up your worldview big time and that's one of the reasons Albert Einstein hated it so much. Can't blame him, I mean, his theory of relativity was supposed to be the one which finally described the true nature of reality and then comes along the double slit experiment and the schrodinger equation which just completely butt raped our current understanding of reality at the time and it's still puzzling today, although many scientists are searching for a grand unified theory which should explain the relationship between relativity and quantum mechanics.

Some of its philosophical implications are fucked up. Many believe it means reality doesn't exist but only our minds do, some believe it means there are parallel timelines/universes to our own, some believe its due to higher dimensions geometrically interacting with ours, some even believe it could imply our universe has some sort of pan-psyche to it. Yeah it gets really fucked. It just goes to show that we don't know shit about our universe.

"If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet."
