The popular practice in Hollywood (and sometimes, in Asian cinema) of using rapid-fire editing to compensate for sloppy fight choreography or actors who are poor martial artists. The key signs of edit-fu are frequent shot changes in between moves (and sometimes during them, if it's really bad) and is sometimes accompanied by a close-up, shaky camera do further prevent the audience from actually looking at the fight.
Person 1: Hey did you see that martial arts movie starring that underwear model who was fighting all the ninjas?
Person 2: Yeah, and it sucked. The story was lame, no-one could act, and not even the fights were any good because they used so much edit-fu.
