When dating if you have sex with a woman more then five times she considers you two to be in a relationship. No matter from the outset it was agreed upon there were no strings attached there are still strings attached whether the male thinks so or not.
Dude, you slept with her how many times? You shoulda stuck to the hand rule!

The standard against which optimal breast size is gauged in seeking a suitable mate, etc.

The optimal breast size is equal to the amount that can be fit in one's hand; any less is not enough and any more is excessive, wasteful, and unnecessary.

The curve follows a sharp Gaussian/CauchyLorentz function and distribution.

f (x; 0,1) = 1 / π (1 + π^2)

This is also known as the Breast-Volarity curve.
Person 1: Wow, she has exquisite breasts.

Person 2: Eh, they're too large.

Person 1: Nonsense!

Person 2: Don't forget the Hand Rule.
Person 1: Ahhh, good call.

A series of gang signs used as dog whistles by physicists to communicate with one another. There are several iterations corresponding to different affiliations.

The most common and simple versions usually involve holding one's right arm out, curling the fingers inward toward the torso, and pointing the thumb upward. This is often (but not always) accompanied by the member looking up in the direction their thumb is pointing. At times this may be inverted, with the thumb pointing downward.

Adherents of various sects differ on dogma, but universally agree on the "Power" of physics in the world.
I just had a student ask me if which hand they were supposed to use for the right hand rule.

A porven method to guarantee sexual intercourse. It is as follows:
Left Hand Rule:
First thing you have to do. You have to lay on the left side of the bed.
Then you take your left hand and slap it across her belly. Don't slap it hard, just kinda place it there. And then you take the right side of your head and put it on her shoulder so you can look up at her. Then you take your left hand and turn it vertically, with your fingertips pointing in the direction of the vaginal area. Then you take your top 4 fingers and feel the waist band. Thats to let her know that you are there. Now at this point, you look up again to see if she is looking at you. If she is not looking at you, this gives you clearance to slide toward the cleft of the clitoris. You take your middle finger, and you start to slide it down adn you are searching for the clitoris. Only the middle finger. Once again you look up, to see if she is looking at you, you have have past the second clearance area. Now that you have reached the clitoris she has gave you clearance, so you take the index finger and the middle finger and you hook them around. Now what you do is you take those 2 fingers and stir them around in the vagina like it's some hot chocolate.Now here is the final look, you gonna go ahead and look at her again. And at this point she should not be looking at you and moving around making little noises cause it feels good.Now, what you gonna do now while your left hand is down there, you take the right hand and proceed to take the pants off. She should start assisting you in the removal of the pants.At that point her legs should part like the RED SEA. Remove Left hand, insert penis. This plan is 100% fool proof.

This rule states that when masturbating with your right hand your thumb points in the direction the spooge will fly and your curled fingers will point in the direction your dick will bend if you jerk it with the right hand all the time.

There is actually a corresponding left hand rule that works the exact same way.
"It's good to be an ambitextrious masturbater.If you don't switch from your right hand once in awhile the right hand rule will tell you which way your dick will get bent."

By making your middle finger and thumb into the shape of an L, the length of your dick is the diagonal distance between the two tips. Great for comparing dick sizes with the homies without having to go through the hassle of doing it normally.

A cool gang hand sign Dr Dara O' Hogan taught his physics class in oaks park high school, used to refer to the good old days when Dr O' Hogan used to teach physics (he was a good guy but he couldn't teach to save his life (nobody learnt anything))
