No, not what Canon users do to Nikon reviews, but rather the art of following a moving subject at a relatively slow shutter speed to blur the background, giving the impression of speed. This is probably not a technique we might use often at WDW but it could be useful for something like "Lights, Motors, Yawn" 
The idea is to use a shutter speed maybe about 4 steps slower than normal and track the motion of the object. Some of the techniques I have found to work include:
prefocus, even fast focusing L lenses have trouble locking onto a really fast object in time;
follow through, it makes for a smoother capture.
I tested some of these ideas recently at a vintage auto race, with very fast moving objects not too far away. My 70-200 L was sometimes capable of locking onto a car, but not always. A shutter speed of 1/125 to 1/250 seemed to work well, where I often used 1/1000 to freeze the motion.
