Implicating bent_over -> prostration.

Reason: Proper term for submissive pose. Would help many a fap-google, too, by combining with kneeling.

bent_over: "Images or Animations in which a character is leaning over at a right angle with their back bent."

This is not always submissive. See, for example, post #308905. Furthermore, "prostration" is not a generic term for any submissive pose. It has a specific meaning, which bent_over does not match.
