“I find the idea of one hot man appealing, so I consequently find the idea of two hot men appealing, too,” wrote anonymous user Dark Twin in her 2004 attempt at explaining why she, a straight woman, enjoys slash fiction. “But when these two men start getting hot together, my enjoyment of the scenario isn’t doubled, it explodes exponentially.” Also known as slash or slashfic, this is where fans write stories about two (often male, mainly heterosexual) characters from popular media who suddenly realize they’ve fallen for each other. In many cases, sex — and lots of it — follows. And cis women dominate the genre, from fansites to, increasingly, TikTok.
