What is the definition of Radius Weapon?

A 'radius weapon' is like a cosmic pizza slice that explodes in all directions with the power to obliterate a target area. It's essentially a supercharged, spatially-limited grenade that says, "I'll just blast your enemy from one end of the universe to the other, without even trying!"
