When a human crouches upon all four limbs, forearms to the ground (or bed), and their rump is aimed up at the sky like a prized pig exposing the undercarriage.
To Hog-crouch, hog-crouching.

To Hog-crouch, hogcrouching.

As I came back into the bedroom, I found Sally hog-crouching on the end of the bed.
