How do you define the Hippo?

This question is for all members.

What makes it a Hippo as opposed to the Modern, the Owen, or something else?

I define the Hippo as this formation:

That's what I would consider the Hippo. The Modern Defense and the Owen's Defense can lead to the Hippo, but until I have something that resembles that formation (or something close to it with the fianchettoed bishops and the knights in the center), I would say that I'm still in the process of going for the Hippo.
