The Thing That Should Not Be 

A heavily underappreciated yet kick-ass song by Metallica. Written by James Hetfield, Lars Ulrich, and Kirk Hammet, it's track three of eight on there album, "Master of Puppets".

Messenger of fear in sight
Dark deception kills the light

Hybrid children watch the sea
Pray for father, roaming free

Fearless wretch
Insanity
He watches
Lurking beneath the sea
Great old one
Forbidden site
He searches
Hunter of the shadows is rising
Immortal
In madness you dwell

Crawling chaos underground
Cult has summoned twisted sound

Out from ruins once possessed
Fallen city, living death

Fearless wretch
Insanity
He watches
Lurking beneath the sea
Timeless sleep
Has been upset
He awakens
Hunter of the shadows is rising
Immortal
In madness you dwell
In madness you dwell

Not dead which eternal lie
Stranger eons, death may die

Drain you of your sanity
Face the thing that should not be

Fearless wretch
Insanity
He watches
Lurking beneath the sea
Great old one
Forbidden site
He searches
Hunter of the shadows is rising
Immortal
In madness you dwell

I should not have nutted to that. 

When you look at very fucked up porn/yiff, nut to it, and then regret looking at whatever you looked at.

Guy 1 nuts to some fucked up yiff he found on e621.
Guy 1 then immediately regrets looking at said art.
Guy 1: I should not have nutted to that. DEFINITELY should not have nutted to that.

The Thing That Should Not Be 

An extremely great song in the Metallica album "Master of Puppets" written by James Hetfeild and Lars Ulrich before Metallica's downfall in 1990.

The name "The Thing That Should Not Be" Refers to H. P. Lovecraft's mythical "Great Old Ones" , Dagon and Cthulhu, who in ancient times were worshiped as gods. They were imprisoned under the ocean, and all their lands sunk down into an endless void. When the stars are aligned in the right place, them and their dead cities rise out of the sea and the humans who behold them then are permanently insane.
