We were in the car yesterday heading to a Chinese Buffet for dinner when we started talking about fan-fiction. He asked what I was thinking and I told him I wanted to start writing again, but I'll probably write in fan-fiction. He asked what kind of stuff I used to write about and I told him, it was mostly het, some slash, and a few femmeslash.
"Oh, so like murder-mystery? Or horror?" He asked. I gave him a blank look.
"Huh? I mean some horror?"
"You said slash..." I started laughing and explained to him that slash/femmeslash was like yaoi and yuri. He got it then, and I started explaining some other terms to him like mpreg, lemon (dated), one-shot, alt-u, etc. It surprised me how he never ran across any of this, and he used to read fan-fiction every now and again when he was in high school.
