Is there a Meh user icon legend?

As the title says. I see all kinds of them, some of which I’ve figured out (Goat, past Goat, VMP member, etc.) but there are many more I’m not familiar with.

Speaking of user icons, I wish I could upload an avatar of my squeaky wolf self that would show up next to my name. :B
