An absurdly large number.

Here we will display absurdly large numbers 
Instead of writing this: Busy Beaver to the Busy Beaver..... 
BB(BB(BB(BB(BB(BB.......)))))
I will create a new function called: RBB that describes how many Busy Beavers stack on top of eachother. RBB stands for Repeated Busy Beaver and it's a repeated rayo's function (BB) operation. 
Let's take an example:
RBB(L1,L2)
The variable "L" means levels. 
L1 stands for how many busy beavers are repeated.
L2 stands for the number in the last busy beaver repetition. It works like this: RBB(2,n)= BB(BB(n))
RBB(4,2) = BB(BB(BB(BB(2))))
----
An absurdly large number is something like this:
RBB(RBB(RBB(100,100),100),100)
Another (but smaller) absurdly large number:
RBB(1919,1919) or Beaverplex
== Extension 1 ==
Instead of using busy beaver just use frantic frog so it's RFF. Frantic Frog is more powerful and can stack
Using this, you can make Frogplex, or RFF(1919,1919) and this means that 1919 Frantic Frogs that are stacked on eachother.
== Extension 2 ==
L3 : Number of times RFF is stacked on itself.
L4: Number of times L3 is looped
Using this, you can make "frogplexus" or RFF(1919,1919,1919,1919)
A way to shorten it would be like this:
If all entries are the same number just do RFF(1919[4]). Much shorter version of frogplexus.
== Extension 3 ==
One insanely large function would be:
This modifies how many levels "L's" RFF has. Warning: X must: be over 2 and must not be a decimal for the function to work. 
\Re \kappa(x) = RFF(1919[x])
\Re \kappa(2) = RFF(1919,1919) Frogplex
\Re \kappa(4) = RFF(1919,1919,1919,1919)Frogplexus
Everything that has L4 and above shows the number of times the previous "L" has been looped. 
Example: L5 shows the number of times L4 is looped. 
L6 shows how much L5 is looped and so on. 
Impossible to write here numbers related to \Re \kappa(x) : 
\Re \kappa(10^{100^9}) 
\Re \kappa(10000^{100000^{1000000^{1000000}}}) 
\Re \kappa( RFF(1919[4]) ) 
\Re \kappa(\Re \kappa(10^{100000})) 
\Re\kappa(\Re\kappa(\Re\kappa(10^{10^{\Re\kappa}(10^{100^9})}))) (named Frogimus)
=== Extension 3.1 ===
Just repeating the \Re \kappa(x) function on itself can generate enormous, gargantuan numbers, but we can do better...
An extension and abbreviation is written like this: \Re \kappa(10^{100})[100,000] with there being 100,000 nestations/repetitions of \Re \kappa(10^{100}) 
=== Extension 3.2 ===
\Re \kappa(10^{100})[10^{100},10^{100}]: rep, rep,... [X,Y] x rep Y rep ext.
arbitrarily large number of rep -> rep -> rep as Y
