One who bends their legs backwards in a locked position when standing straight up. Their legs are not bent all the way, it is bent enough to see a slight curve in the leg. It is not known what causes this phenomenon, but looks very messed up.
When a person is standing straight up and locks their legs. With most people, they lock in a straight-up position. With backwards standers, the leg is bent backwards farther than any leg should go.
