Have we ever had a YACFer in this thread?
Today I was talking with someone about names that can be both male and female and how, over time, they seem to all end up as only female; Hilary, Lesley, Kim... This person then told me that in the 1970s they'd had a flatmate who was gay and from him they'd known that, during that decade, lots of gay women took on the name Kim as a sort of lesbian trend. Maybe even a secret recognition code? So, yes, I know it doesn't quite fit on at least two counts, but near enough for a random thread.
Perhaps more interestingly (but not relevant to the thread) was that this came about because we were talking about a male Kim known to both of us (I've no idea if he's gay, straight or whatever, that's not the point here), and she said he'd adopted the name Kim as an adult, having rejected his family and become an anarchist. At the same time he changed his surname to Shelley, presumably after Percy Bysshe (and we think unusual names are a recent trend!), so he's Kim Shelley.
