your simply losing traction, if you have the balls for it, stepping on the gas and accelerating will sometimes get your traction back, since the wheels have caught back up to the speed your slipping.
I have done this exact thing, but it does require stones as you note. It goes against everything your "pucker factor" is telling you to do. You want to stomp the brakes, which does zero good, but if you can accelerate the tires you can sometimes regain traction and hopefully be on more solid surface to start the gentle slowing down process. But a better strategy is usually drop the bucket (lip turned up) to try to slow down, or drop a ground engaging implement.
