Is there a western word for this? where a woman is in a crab or half squat stance, arms up just putting everything on display? Sometimes they'll move their hips or bounce their body in that pose.

I only see it on hentai or when cosplayers are ironically doing the pose.

In most photos I see models usually leaning against something, doing a full squat, sitting, or kneeling. The pose entirely is usually unflattering. This one is pretty close if she wasn't sitting on something
