Arm_around_leg

People use arm around leg for both arm around own (post #8127386) and another's leg (post #10239152). They also use the tag for hugging own leg or hugging own legs too, like post #10255546.

This makes the tag rather ambiguous. I think we may need to split it between arm_around_own_leg and arm_around_another's_leg.

how about hugging own leg and hugging own legs?
oh, maybe we should imply arm around leg to hugging own legs

We could do away with hugging own leg, hugging own legs, and hugging another's leg and instead use arm_around_own_leg, arm_around_own_legs, arm_around_another's_leg, arm_around_another's_legs, arms_around_own_leg, arms_around_own_legs, arms_around_another's_leg, arms_around_another's_legs.

That should be specific enough for all use cases. That would make 8 new tags from just 3 tags though.
