What is the definition of Return Weapon?

A 'eturn weapon' is like the ultimate retribution of the universe, but instead of a feather duster, it's a firearm or a bomb that's been casually left behind in an abandoned alleyway. It's essentially, "You got away with the bad stuff, now you're paying for it by being outfitted with a little bit of your own personal menace."

Here's an unsettling example sentence: "After the prankster accidentally set the entire town ablaze, they decided to return his 'eturn weapon' - a trusty old bow and arrow - by replacing it with a nuclear missile, just to make sure he paid for his messy humor."
