BUR #9890 has been rejected.
create alias open_pants -> open_fly
create alias open_shorts -> open_fly
Redundant tags, even after reading the wiki of each tag
open fly: When the fly (crotch) of a character's pants or shorts is unzipped or unbuttoned.
open pants: Pants with an open fly.
open_shorts: Shorts with an open fly.
the "open fly" tag covers all possible alternatives, no matter if it is shorts or pants, unbuttoned or unzipped.
even open_fly tag already has an aliased other alternative tag (unbuttoned_pants)
I can't think of any other way where a shorts or pants can be opened without opening from the front.
and before they say that tearing a pants could be considered an "open pants", in those situations torn_clothes could be used instead.
