So. Forgive me for being dumb, but what is gen fic?

And LM- give me some LJS plot bunnies so I can write something next week. Anything but NW or M/M slash. Believe me, there's a reason why I can't write M/M right now... but I shall fulfill that desire via Secret Slasha. So yeah. Plotbunnies, please!

Next week, I get to start writing again. Ahhh. Feels good.
