Cottaging
I need to hand in my gay card, it's obviously been too long since I studied for the entrance exam. Pretty sure this was unintentional on RR's part, but hilarious given the post-photo shoot shower scene and the story's climax at the cottage:
>Cottaging is a gay slang term, originating from the United Kingdom, referring to anonymous sex between men in a public lavatory (a "cottage"^([1]) or "tea-room"^([2])),^([3]) or cruising for sexual partners with the intention of having sex elsewhere.^([4])^([5]) The term has its roots in self-contained English toilet blocks resembling small cottages in their appearance; in the English cant language of Polari this became a double entendre by gay men referring to sexual encounters.

FYI I've only ever heard the term used by drag queens, and that was long ago.
