Okay, I just made it up. So? It's AGN, so it's AGN EDITION.

To play, I'll put up a word. You have to reply with the first thing you think of. Then, you put up a word. So, if I put genitals, somebody can reply with "pink and purple polka dots". So they put up symbiosis, and someone replies with "something scientific described with a picture or symbol". Then he puts a word, and so on. Sound fun?

I'll start (obviously).
