Is that from his speech today???
It’s the Clintonian “I’m concerned” lip pursing.
Give him a week, he’ll be biting the lower lip next.
BTW: Is he growing a ‘stache?
I’ll be curious to see this no-fly zone exercised. I predicted it would never happen. Let’s see what goes down now.
Pursed
Lips which are pulled inwards from all directions are an indication of tension and may indicate frustration or disapproval.
Pursed lips are a classic sign of anger, including when it is suppressed. It is effectively holding the mouth shut to prevent the person saying what they feel like saying. This may also be an indication of lying or withholding the truth as the person stops themselves from telling the truth.
Flattened
Lips which are kept horizontal but squeezed flat are an exaggerated closing of the mouth and hence indicate a repressed desire to speak. This indicate disapproval ('If I spoke I would be very critical, which I do not want to be'). It can also indicate frustration ('I want to speak, but others are speaking and I feel I should wait').
This is his typical combo Mussolini-girly-boy pout.
Here's an odd factoid. I entered Obama+pout in Google image search to find that "no such document exists". Must be union sanitation workers slogging away over there.
