Originally a great idea by EWild, I'm making the AGN verison here.
It's the same as The Person Above Me, except that you have to tell something you hate about the person who posted before you.
You don't neccesarily have to tell the truth.

Ex: I hate bdb2007 (who should have named himself UpbeatPenguin) because his screen name sucks.

So go ahead...and hate everyone.
