BUR #31718 has been approved by @nonamethanks.
create alias clothes_on/clothes_off -> clothes_on_and_off
create alias expectations/reality -> expectation_vs._reality
create alias big_pants/big_jakt_(meme) -> big_pant_or_big_jakt_(meme)
Unless there is '/' in an official work or original source(So I excluded like this/like that),I think we should choose with the '*_and_*' naming, which is already dominant in danbooru.
Well, maybe a few years after there will be a BUR that says the exact opposite of what this BUR said here, but I doubt it'll be approved.
