Marie Kondo is a Japanese organising consultant and author, whose 2011 book, "The Life-Changing Magic of Tidying Up" described the "KonMari" method of tidying up.
This involves pulling together your belongings in one place, one category at a time. Once gathered, you keep only items that "spark joy" discarding anything that does not "spark joy".
This became very fashionable, and her name became used as a verb: to Marie-Kondo something was to (brutally) tidy and organise it.
