What is the definition of Retrieved Fumes?

"Retrieved fumes" is like a cosmic cleanup crew that comes back for the stinky remnants of a space battle or a particularly odoriferous factory accident. Picture this: After a massive rocket launch, the atmosphere gets a bit... let's call it "sparkly." The retrieval crew, made up of superheroes of odor, swoops in to pick up those pesky fumes before they turn our planet into a stink bomb.
