Rambiance 

The ambiance of battle, particularly like those featured in the Rambo films. Something exudes Rambiance when the smell of blood and burnt flesh is accompanied by the din of gunfire, explosions, and the cries of the innocent.

While walking through the streets of Mogadishu Carl remarked "Man, this place has some serious Rambiance going on, am I right?"
"You totally are," replied Phillip, as he threw a grenade into a nearby bombed-out schoolhouse.

Absolute Radiance

The hardest boss you will ever face and is the most biggest pain in a 2D game
The requirements are insanely difficult and if you aren’t prepared then have fun going through every boss in the game again but before you can do that you have to do all the pantheons. If your a uncultured swine and don’t know what a pantheon in Hollow Knight is then why are you even reading this, it’s basically a boss rush and that all I’m saying about it. Except that the one you do before the final pantheon is very difficult because a insanely buffed version of the “final boss” of the game is the last boss you fight before unlocking the final pantheon. When you get to the last pantheon you go through every single boss and even the buffed versions of them, right before you fight the Absolute Radiance you fight a boss that is either harder or and hard as her and that boss is Nightmare King Grimm. If you somehow manage to beat him you finally fight Absolute Radiance.

Gamer: “YES FINALLY AFTER A WHOLE MONTH OF TRYING I DID IT, BRING IT ON RADIANCE”
*Absolute Radiance continues to make Gamer to fall in the void, get hit by 2 light pillars, and dies to light sword*
Gamer: “...”
*Throws computer out window*

zero-point radiance 

An omnipresent type of radiation.
It has not yet been discovered what causes this radiation, if something actually causes it.

Remove everything removable and you'll still have zero-point radiation.
