Crashes often occur when cyclists get squeezed together. If two cyclists got squeezed together while riding slightly staggered from each other, the foot of cyclist in the left rear could go into the back of the rear rotor of the rider to the right front. Since the rear wheel is still on the road and spinning, the rotor would be turning quickly and with a lot of torque. If the two cyclists were in this position for 7 ft. of forward motion, the wheel would turn a complete revolution.
While not the same thing, I once had a cyclist put his front skewer into my rear spokes. Out of the 20 spokes of the rear wheel, 7 were broken, and an additional 6 were damaged. So, the skewer was into my wheel for most of a revolution (fortunately, I didn't go down, and rolled to a stop).
However, as it was the cyclist's left shoe that got cut (the right shoe would be closest to another rider's disc rotors), I can't think of an easy way for this to happen.
