Tag Alias/Discussion: back_hug <-> hug_from_behind

Requesting that hug_from_behind be aliased to back_hug or vice-versa.

Reason: they seem to be the same thing. I guess back_hug would be preferred since it has many more posts than the other, but hug_from_behind may be better due to clarity. If it happens that they are different, then some cleanup needs to be done and wikis written.

If there is no difference, then +1 for hug_from_behind. That is also if there would be no problems moving the back_hug -> hug implication.

You can hug someone's head or hips or whatever from behind (post #700922). I'm okay with subsuming them all into hug_from_behind if there's no particular outcry in favor of keeping backs separate though.
