megalomanic 

To be full of oneself, haughty. One who thinks they are the best and most important person in the universe. Self absorbed.

That megalomanic SOB thinks hes just it!

The feeling of your sins crawling down your back

Megalovania 

"Megalovania" is the Greek word for "Megalomania", which means "obsession with the exercise of power, especially in the domination of others". It is also the name of the song played when you fight Sans in Undertale. The song might be called this to relate to the abuse of your power to reset and alter the timelines.

"His megalovania was clear to us all"

Megalovania Effect

The Megalovania Effect:
Any song that is modified by any means but majority to most of the modified songs still sounds really good. At this point, We can conclude Megalovania is the first to achieve that in human history.

Epic Gamer: Yooo y'know what's sick?

Epic Memer: What bro?

Epic Gamer: That no matter how much you edit megalovania to make it sound like shit, it stills sounds good!

Megalovania is the song that plays when you fight Sans. The final boss of the Genocide Route of Undertale. The word means the feeling of sins crawling on your back.

I just committed all 7 deadly sins. I have Megalovania.
