Representative Anthony Weiner gives us a beautiful example of an inward lip roll. With his texting scandal and in particular, the elicit photos which are at the center of the controversy, this sign is one of several to be expected. The inward lip roll is a sign of increased anxiety and stress. It often has a component of anger and/or effort-related stress - e.g. He's trying hard not to exhibit anger or embarrassment. The lips are an extremely sensitive tissue and touching one or both with the hand/fingers, tongue, teeth or with the other lip is an example of a manipulator/adaptor/pacifier.
