As the title states, ban the person above you! It's pretty self-explanatory. But if you need an example, here you go...
Ex:
Player 2: I ban you because I just banned you.
Player 3: Well I ban you because no, I just banned you.
Etc...
You can come up with whatever dumb reason you'd like. Just keep in mind, this is only a game! So I'll start off.
I ban the site banner above me since there is no one above me to ban.
~And yes, I felt TB needed a game like this 'cause we need more games. I also found it surprising we didnt have this game already...
