Newton's balls

Originally an experiment demonstrating the principle of conservation of momentum, Newton's balls are five metal balls suspended in line by fine wire or string. When one ball impacts the rest, momentum is conserved and the ball at the other end is knocked into the air.
Alternatively, Newton's balls can be used to describe a sexual situation. When two men engage in anal sex in the doggy style position their balls slap together, creating an effect much like that described above. Gay people often feel that such a situation is baroque.

"Bastian and Gabe got the Newton's Balls effect happening last night, I could hear it from next door!"

Newton's 69th Law 

A scientific law formulated by Sir Isaac Newton telling the likelyhood of a female having sexual relations with a male, as expressed in the equation:

100{2*lM(d^2)l/(v-S)}/G

where:
M= Muscle definition
d= douchebagness
v= Moral Values
S= slut value
G=Girl's hotness

Jon: Do you think Ashley will fuck Michael tonight?
Matt: No, he's not enough of a douchebag, so it does not satisfy Newton's 69th Law.

Newton's Second Law of Motion 

The law of force and acceleration states that an object depends upon the net force acting upon the object and the mass of the object. Also know in simpler words as an object's acceleration depends on the net force acting upon the object and its mass. This was done by thereal lola

Dude: Why is my car zooming?
Me, an intellectual: Because of the force and it weight and the Newton's second law of motion
dude: WHOA

Newton's 60th Law 

After you finish your placements in Overwatch, you shall lose 7 matches in a row no matter what happens.

We must stop doing our placement matches, otherwise Newton's 60th Law will fuck us over.

Newton's Turd Law 

Newton's Turd Law is a physical law described by Isaac Newton, a 16th-century British physicist and mathematician, dedicated to describing the kinetic behavior of a semi-rigid externally unconstrained fecal system of particles forming a semi-rigid body, otherwise known as a Turd. Specifically, this law focuses on the behavior of a Turd post-freefall collision.

This law is part of a set, known colloquially as Newton's Laws, collectively discovered by Newton when observing that his Turds accelerated downwards and not sideways or diagonal.

This law states that 'for every action there is an equal and opposite reaction'.

Newton's Turd Law is the explanation for water splashback when taking a shit, why larger shits have appropriately larger splashbacks, and why gigantic shits could break the toilet.

We are looking forward to hosting the prestigious international physics-chemistry conference in which participants will have the opportunity to present experimental data and physical samples involving Newton's Turd Law.

If you poop in my bedroom, I will be forced by the physical law of nature known as Newton's Turd Law to defecate in your bedroom, equally by total quantity in volume, assuming a similar density of substance.

Newton's 4th Law

"For every reaction, there is a female overreaction"

Newton's 4th Law is the least known of all, but perhaps his most accurate one.

- Hey Joey heard you got in a fight with your girl.
- What can I say, man, Newton's 4th Law made its effect.

Newton's Cradle

Describing the swinging action of at least 2 men's testicles as the slap against each other during anal sex.

They were at it so hard that their balls' were bouncing like a Newton's Cradle.
