What is the definition of Maintenance Fumes?

"Maintenance fumes are like the unseen, invisible, and slightly toxic byproducts of our human endeavor to keep our homes or offices looking brand new. They're the smell of broken appliances, rusting pipes, and the collective sigh of frustration from people who can't seem to fix their own existential crises."

Here's a darkly humorous example sentence: "The janitor's 'aintenance fumes' couldn't handle the scent of his own failed attempt at DIY home improvement, so they decided to call in the real deal: a ghostly figure dressed as a vacuum cleaner, waving a broom made of duct tape."
