Last month Ted Nugent infamously called President Barack Obama a "subhuman mongrel". The video above includes Nugent using this slur. What follows is a partial body language analysis.
At the 0:56 mark, Nugent displays several nonverbal signals consistent with anger. When two or more body language configurations are seen simultaneously or nearly so, this is termed a "Cluster".
Here, the rocker juts his jaw forward while clenching it at the same time. There is also a dramatic thinning of his lips along with a tightening of the "mustache area".
At the 0:57 mark, we see demonstrated an extremely prototypical thinning of the lips. Even when seen alone, this extreme straight horizontal lip sign is a very reliable red flag for anger.
Nugent knows he's pushing it. Thus we see several times in this short clip (here a few tenths of a second after the photo immediately above), an example of a "Tongue Jut" (aka "Lizard Tongue") - here indicating "I've been bad", "I got caught", "I did a foolish thing" or "I got away with something".
Depending on the other nonverbals with which it is clustered it can signal excitement or self-depreciating emotions.
