Concept: Big guns equals big trouble ahead?

Hey guys, something I've been wondering about recently. 
 
In a game where right out of the blue you come across a big weapon, be it a gun, sword or an object. It signifies that immediately afterwards is a boss. Is this concept already on the site? And if so, what is it called?
 
For example, in FEAR you stumble across the multi-rocket cannon for the very first time, only to be immediately attacked by a huge mech, here that weapon becomes incredibly useful.

Weapon + premonition = weaponition?

This is definitely a thing and should have a concept page. 

Are we gonna have to come up with a name before making a concept page?

Gun+Hunch=Gunch?
 
 
Am I trying too hard?

This is the kind of thing that makes me wish we had cliches on Giant Bomb, too.

A name and a clear definition would be appropriate before creating a page.

" @iAmJohn: well Concepts kinda fill that role. "

Not different enough from stock up area

And you guys need to quit it with the portmanteaus. They're lazy and obtuse. If you said one of those words to another person they'd have no clue what the concept meant, and certainly no idea how to search for it.

" A name and a clear definition would be appropriate before creating a page. "

It's described on TV Tropes as Suspicious Video Game Generosity.
 
The greatest I've ever seen this applied was in two sections in Silent Hill 2.  One was an elevator loaded with ammo.  You usually aren't able to move in elevators, so you activate this big service elevator, it begins slowly moving downwards, and there is ammo everywhere.  Every video game instinct in you says you are about to get into a terrifying close quarters fight, so you get on edge.  The elevator goes down... down... down... after about thirty seconds it stops... and you get off.  But the entire time you are scared.  They did that with just ammo and an elevator.
 
The other part is before your boss fight with TWO Pyramid Heads... there is a save point.  But not just any save point.  There are NINE save points arranged on a wall.  The game is telling you in the most elegant and medium-specific way possible.

You talking about the health+ammo rooms before a boss? Restibule. Slaytrium.

" Not different enough from stock up area  http://www.giantbomb.com/stock-up-area/92-5393/  

Well if it's not different enough then it's not different enough. I didn't know there was a stock up room page. Maybe I'll go over there and expand that page to include this.

" @Insectecutor: Not necessarily, I mean when you stumble upon a super weapon you've not yet encountered. Where as those stock up rooms are ammo for weapons you already have.  FEAR has stock up rooms too. But the time when you find the rocket launcher it's just sitting alone in the hallway. "

Or, at least, even if you already have the gun, if you walk into a room where there is tons of ammo and spare rockets and grenades, you know for sure that something big and bad is coming up.

I've been thinking about it so I'll propose the following...
 

• Stock Up Area

• New Weapon Introduction

" You talking about the health+ammo rooms before a boss? Restibule. Slaytrium. "

" @rateoforange:  Lazy and obtuse? Welcome to the English language. 

Just throwing out another example of this from Bioshock:
 

If I may? Warshadowing. (foreshadowing + Weapon of war, I know, I'm a genius)
 
And then, having contributed nothing of value, our hero vanishes into the night...
