What the buck?

I figure this reminded me of the Rocky Horror show, what else that has craziness like this?

Pinkie: It was great when it all began!  
I was a regula rainbow fan,  
But it was was over when she took control,  
and started working on a muscle colt.  
Now the only thing that gives me hope, is my love of a cross eyed dope,  
Derpy in ma world keeps me safe from my trouble and pain.
 
Big Mack: I am just seven hours old,  
Truly beautiful, to behold.  
But somebody should be told, my labedo hasn’t been controlled.  
Now the only thing I’ve come to trust,  
Is a rainbooming, rush of lust.  
Derpy in my world keeps me safe from my trouble and pain.
 
Twilight:It’s beyond me  
Heeeelp me mommy!  
What’s this? Well lets see,  
I feel silly  
What’s come over me?  
Ooh! Here it comes again!
 
Fluttershy: Whoa-oh-oh!  
I feel released! Bad times deceased!  
My confidence is increased!  
You’re gonna love meee!  
The game has been disbanded!  
My mind has been expanded!  
It’s a gas that rainbow’s landed!  
Her lust is so sincere!

so  
Twi = brad  
Flutters = jannet  
pinkie = columbia  
big mac = rocky  
and RD = frank
 
is that right?

I’m a wild and untamed thing  
I’m a bee with a deadly sting  
You get a hit and your mind goes PING  
Your heart will thump and your blood will sing  
So let the party and the sound rock on  
We’re gonna shake it ’till the life has gone  
Rose tint my world, keep me safe from my trouble and pain

My life is complete now.
