That's the sound I made this afternoon when I opened the front door, stepped onto the pavement, and immediately executed a violent 90 degree rearward tilt maneuver (often known as "slipping.")
Apparently a surface with a unexpectedly low friction as been deposited on many horizontal surfaces, its existence seemingly due to ground materials retaining their low temperatures from the previous evening, the current ~32f (0c) surface air temperature, and a layer of vapor laden warmer air above causing liquid dihydrogen monoxide to condense and fall to the Earth. It seems to be solidifying upon contact with surfaces that are below its freezing point, and has thus formed an unsightly and quite hazardous layer on many objects, including my car and the roads.
