Infield Fly Rule

Baseball sexual metaphor for when there's an unequal ratio of males and females at a party and one member of the dominant group leaves to create an equal ratio.

John called the infield fly rule at the party and left so it didn't turn into a sausage fest.

The Eye Contact Rule

The Eye Contact Rule is simple. If one finds that they are engaging in a homosexual act, as long as they don't make eye contact it isn't gay.

Friend 1: Bro did you suck his dick?

Friend 2: Yeah
Friend 1: Bro you're fucking gay as shit

Friend 2: It isn't gay, we didn't make eye contact. The Eye Contact Rule applies.

Or

"It isn't gay if you don't look them in the eyes though."

The Dr. Rule

An entirely unwritten and yet widely accepted variation to the Eleven Minute Rule. The Dr. Rule states that if you are sitting in class for fifteen minutes (rather than the eleven provided a professor without a doctorate) and no professor has shown up, you are allowed to leave class without penalty.

Guy 1: "Dude, it's been 11 minutes we can totally leave class now!"

Guy 2: "No man she's a Doctor, we have to wait four more minutes."

Guy 1: "Oh right....the Dr. Rule....where is that actually written?"

chain rule

In calculus, the chain rule is used to differentiate compositions of functions. It states that for any function f which is dependent on a variable u, and u is a function of a second variable x, then f is a function of x.

In Set Theory:

f(u)=u V u(x)=x V Vf(x)

In Calculus:

df/dx = du/dx(dx/du)

to differentiate (x+1)^2, one could multiply this out and apply the sum rule (derivative of a sum is the sum of the derivatives); but what if it were (x+1)^55? Suddenly the multipling out doesn't look so nice. To apply the chain rule, we must first define the functions. Let f(x)=(x+1)^55 and u=(x+1). Therefore f(x)=u^55. By the chain rule:
df/dx = df/du(du/dx)
df/dx = d/du(u^55)(du/dx)
df/dx = 55u(du/dx)
We earlier defined the variable "u" as (x+1). Now we substitute this in.
df/dx = 55(x+1)d/dx(x+1)
df/dx = 55x+55(1)
df/dx = 55x+55
