You'll remember during the Dem primary when Obama's middle finger came up and scratched his face while talking to a crowd of supporters about Hilary Clinton, at a particularly tense moment in the contest between the two. 

Here's the video:

Classy.

Obama did this on purpose.  He's from Hawaii.  This is precisely how this maneuver is executed, in just this type of situation.  The index and ring fingers can just come up so far, curled at about 60% total length, to give you enough room to make the excuse that you didn't mean it.  Similar calculating algorithm is functioning to decide Obama's positions.

Apparently, Korean War POWs put out the finger in DPRK propaganda films...

The finger became an integral part of our anti-propaganda campaign. Any time a camera appeared, so did the fingers. A concern grew among us that sooner or later the Koreans would notice this and ask questions. It was decided that if the question was raised, the answer was to be that the finger was a gesture known as the Hawaiian Good Luck sign, a variation of the Hang Loose gesture.

Obama meant to give Hillary the bird.  There should be zero doubt about this small point.  The people in the audience seemed to understand the moment's meaning precisely.

If Obama did this on purpose, it's a sign of incredible immaturity. If he did it by accident, it's a sign of inexperience. If a president were to make an accidental gesture like that while talking about a foreign leader, for example, it could cause a global uproar. [USNEWS]
