What is the definition of Quantity Weapon?

A 'quantity weapon' is like a super-powered, absurdly over-the-top supply of something that's supposed to be used in a limited way - usually, it's a weapon, but don't forget the non-lethal variety! It's like when you're trying to solve a Rubik's Cube but you've got a whole army of them, each one with a different face and an even more bizarre color scheme.

Here's a chillingly funny example: "The army of quantity weapons charged into the room, each one brandished a 'quantity weapon' shaped like a giant, flailing donut, and the only thing they found was a group of confused toads."
