This is a neat little action word that I never picked up on until I read Mistborn. Since then, however, I've noticed that its used quite a bit. While a fun word to use, it may be a good idea to do so sparingly.
Feint is a French term, but the act of Feinting is to fake an attack or maneuver toward someone with the intent to distract an opponent(s) from the attacker's true target. Say you have two guys picking a fight with you. You go to punch one of them, but then you change your course at the last second and punch the other guy instead. This has been demonstrated in so many movies that I can't recall them all. So yeah. If you see something like that happen in a movie, there is a word for it: Feint.
