Feint, and Improved Feint accomplish more or less the same thing. The fluff for that works, though, since the idea is you distract the bad guy so you can make a more precise attack. The fluff behind "I'll just run around you and hit you from behind, thus gaining my flanking bonus and Sneak Attack damage, despite the fact that there is no earthly reason for you not to spin in place and face me" is silly.
