The bulk update request #11320 is pending approval.

create alias butt_rubbing (93) -> butt_rubbing_(disambiguation) (0)
change category butt_rubbing_(disambiguation) (0) -> invalid

Reason: Per discussion in topic #54597, butt_rubbing is currently used interchangeably for depictions of the butt being rubbed (i.e., rubbing_butt) and of butts rubbing together (i.e., ass_to_ass). It should be invalidated and users directed to the correct tag for the situation.
