The bulk update request #9392 is pending approval.

create alias mooning (1818) -> flashing_butt (79)
create implication flashing_butt (79) -> flashing (9516)
create implication flashing_penis (213) -> flashing (9516)
create implication flashing_panties (200) -> flashing_underwear (18)
create implication flashing_bra (13) -> flashing_underwear (18)
create implication flashing_underwear (18) -> flashing (9516)

Reason: Aliasing mooning to a more standard name, and implying to the broader flashing tag.

(flashing breasts and flashing pussy are already implied)
