Name that mood or emotion.

Arriving in today's mail was a set of Orvan icons from Jim Groat. That was good, as was discovering that in one update or another, PCLinuxOS is now capable of dealing with a flatbed scanner so I could scan the icons.

I had asked for three different moods or emotions and had specified two of them well. The puzzled or bewildered icon is obvious, with Orvan scratching his head. The anger/angry icon is obvious as well. But this one I'm not really sure about. It's certainly a good icon, I just don't know quite how to describe it.

So I ask you. What mood or emotion does that image convey? Or, how would you label that icon?
