The bulk update request #2519 is pending approval.

remove implication butt_grab (45647) -> hand_on_butt (83989)

Reason: butt_grab currently implies hand_on_butt, but it's possible to grab a butt with other appendages, like prehensile feet or talons. post #3347824 for instance is being incorrectly tagged hand_on_butt because one of the characters is grabbing another character's butt with their feet/talons.
