Fast Food Relationships

Gratification of a deeper need, but neither nourishing nor filling. Causes regret, self-loathing and massive weight gain in the long run.
Dang, the last three jerks I dated turned into fast food relationships. I gotta detox or something.

fast food hottie

The thin, flawless, outright sexy girls you see in fast food commercials on television.
Did you see that hot babe on that tv commercial? She looks nothing like the mutant swine you actually see eating at fast food establishments on a regular basis.

*Sigh* I know! Fast food hotties.

Fast Follower Syndrome

A knee jerk reaction to requirements or features requested by a customer which have not been designed nor any realistic time line been set for their implementation, other than expressing the sentiment that said features are "Fast Followers". This syndrome is characterized by the upending of any manageable process that establishes a specification of, a time line for, and allocation resources for implementation.
Dev1: "Hey, did you guys here what the product manager just promised the customer? We're not even done with the original features."
Dev2: "Yeah, and we have no way of knowing of when we're going to do that because there's not even any specifications."
Dev1:"I wish product would attempt to avoid Fast Follower Syndrome."
Dev2:"Yeah we're definitely going to be working over Christmas again."

Fast Growing Hierarchy

The fast growing hierarchy (shortened to FGH) is a method of defining large numbers. It takes in two inputs.

We define f(0,n) = n+1. For example: f(0,3) = 4. Next step is iteration. f(1,n) is f(0,f(0...f(0,n)...)) where f(0,...) is iterated n times. For example, f(1,2) = f(0,f(0,2)) = 4. Same rules for f(m,n).

Now let's define what ordinals are. Very simplified, they're a kind of infinity.
Consider this: |||....|

This has infinite sticks, but there's a 1st stick, 2nd stick... the last stick is the ωth stick. You can have ω+1, ω+2, ω+3 etc too. For our purposes, a limit ordinal is an ordinal that has no finite part at the end (so ω+3 is not a limit ordinal but ω×3 is.).

So how can we use this within FGH? We need to define a fundamental sequence (FS). An FS is the steps we take to reach a new limit ordinal. So the FS for ω is 0,1,2... and for ω×2 it's ω,ω+1,ω+2...
We can write this as: ωn = n, ω×2n = ω+n, ω^2n = ω×n and so on. There are more ordinals, but it'll do for our purposes.

This is not the only system for an FS. There's more, but I cannot fit it in an entry.

Now consider an ordinal α. Now FGH can be defined concretely:
for f(α,n):
if α is 0, it is n+1.
if α is not a limit ordinal, it is f(α-1,f(α-1...f(α-1,n)...)) where f(α-1,...) is iterated n times.
if α is a limit ordinal, it is f(αn,n).

Let's do an example: f(ω,3) = f(3,3) = f(2,f(2,f(2,3))). I know that f(2,n) = n×2^n, so it's 1.804356 × 10^15151336, which is HUGE! Imagine how large f(ω,10) is.
Graham's Number is approximately equal to f(ω+1,3) within the Fast Growing Hierarchy.
