Although it seems like this phrase is already unisex, something about it gives it a feminine tone. I'm looking for a phrase that means "a list a lovers" but can be used by both men and women in contemporary language, leaning towards slang. Any ideas?
Where back in the 1970's somebody would call someone out of their little black book to arrange casual sex, nowadays you make a booty call to one of your your friends with benefits for a hook-up.
But in the post-AIDS era, it's unlikely somebody has so many f.w.b.'s that they need to keep a special list of them. And they probably keep their numbers on their smart phone along with all their other contacts, rather than in a paper booklet.
