BUR #26352 is pending approval.
deprecate ass_grab
ass grab encourages taggers to be lazy and not use either grabbing own ass or grabbing another's ass, as demonstrated by the 16,000 posts in ass_grab -grabbing_own_ass -grabbing_another's_ass.
I don't see the point in having a tag for something as simple as grabbing_another's_ass or grabbing_own_ass
We should deprecate ass grab so that users are encouraged to tag precisely.
