The Mechanical Bull

Get on your girl in a doggy style position, whisper the name of another girl in her ear, and see how long you can stay on

"what did you do with Jessica last night"
"oh we tried the Mechanical bull and I stayed on for 10 seconds"

Quantum Handjob Mechanics

Also known as Quantum Handjob Theory, Quantum Handjob Mechanics is a branch of physics providing a mathematical description of the dual particle-like and wave-like behavior and interaction of the hand and penis.
Quantum Handjob Mechanics describes the time evolution of physical systems via a mathematical structure called the Cum Function. The Cum Function encapsulates the probability that an orgasm is to be reached in a given state at a given time.

Quantum Handjob Mechanics is closely intertwined with the Hymenberg Uncertainty Principle, which relates the fundamental principle that it is impossible to simultaneously measure the present proximity to an orgasm while "determining" the future momentum of a subsequent orgasm with an arbitrary degree of accuracy and certainty.

"Dude, I'm failing Naughty Physics."
"Why?"
"I just can't figure out these equations for Quantum Handjob Mechanics. I'm going to fail that test on three dimensional cum functions..."

mechanical advantage

Making liberal use of vibrators, dildos, anal beads and other sexual devices to make a woman come to orgasm. Used by women in place of a partner, or by a man to a woman because he is too lazy, too stupid or too selfish to do it himself.

Sally wouldn't let me bone her until she came, but thank God for mechanical advantage, eh?

Mechanical Keyboard Enthusiast

You probably have made over 3 expensive builds, scours around group buys, have no money, favorited over 50 keyboard/switch sellers, and you hate mx browns(as you should my objective opinion is great), you are subscribed to all types of mechanical keyboard youtube channels, overall channels, build channels, sound test videos, and all in between. You probably have a very specific preference on what you love in a keyboard, and if someone robbed your house, all you would care about would be your keyboards.

Are you a Mechanical Keyboard Enthusiast?

Slut Mechanic

A low down dirty whore. The type of girl that will literally wrap her legs, lips and ass around anything that looks in her direction. Every time said skank farts, queefs, sneezes or coughs she discharges stale jizz from her body. Effects are increased exponentially when there is liquor nearby.

Jeff: Man who's that drunk bitch?
Nick: Who, Karen? Dude, stay away from her! She's a real slut mechanic.
Jeff: Oh shit really?
Nick: Yeah bro, you might as well dip your dick into a bucket of herpes.

Mike and The Mechanics

Oh, one correction! Paul Carrack is actually the lead singer, he also went off on his own temporary solo career between this band's albums; one in 1985, and another in 1988.

Mike and The Mechanics really should be more well-known

Quantum Genital Mechanics

A field of scientific theory dealing with genitals that are either very small, or very theoretical.

Quantum Genital Mechanics states that Matt has very small genitals, and Mason has very theoretical genitals
