20/10: 20 minutes of cleaning, followed by a 10-minute break.
45/15: Like a 20/10, but longer.
Invisible corner: That area in your home that has had accumulated random shit in it for so long that it’s become part of the landscape. Often found in corners, at the end of counters, or, really, anywhere. It’s been there long enough that your eye doesn’t even register it when you look around.
Marathon: Cleaning for hours on end with no breaks. Marathons are bad.
Sink Zero: No dirty dishes in the sink (or next to it, near it, on it, etc.).
Team UfYH: The people who use the UfYH system.
Wash, dry, and put it away, dammit!: The three steps of laundry and dishes.
