What is the definition of Richards Fumes?

Richards fumes are like the pungent aroma left behind after someone accidentally drank the last of their favorite brand of air freshener, but with a side of existential dread and questionable hygiene. Picture this: "Richards' richards fumes wafted through the deserted office, a morbid testament to his recent overindulgence in the most toxic-smelling candles, making even the coffee machine weep."
