Dead Hard Isn’t Even English

the first time someone told me Dead Hard was a perk, I thought they were a dummy becuase that’s was so grammatically incorrect that I was absolutely astonished, an Eurika moment here people, that it’s actually a thing.
Why exactly is it called “Dead Hard” and not, “Dodge Hard?” Heh?
Whadda heck?
Why?
Weh?

Is it? .... I'm DEAD HARD
It's a Perk's name, you can do whatever you want with names, grammatically correct or not.
For all we know, next set of Perks could have a Perk called "John".
This right here.
Would you rather it be ROCK HARD?
