OK first you say something about the person that posted before you, then something about you, and then something you predict about the next poster. The next poster does NOT have to match your description.
Here's an example.
Sync posts first, then Golden Sonikku says
^ Is red
> Is gold
v is black
and then I post, and I'm not black so he was wrong.
^ Is an admin
> makes comics
v has fuzzy sprites
On and on like that. Hre's my actual post.
^ Doesn't exist
> exists
v likes pie
