disembodied feet
Used for when the foot is not attached to a body. This is most often because the rest of the body is offscreen, but it might just be floating there for no particular reason.
Not to be confused with severed_foot, which has evidence of amputation, or detached_foot, which is re-attachable, as in part of a robot.
