I bring this idea over from Penn basketball games, because it works pretty well there and I think it would look really cool in 139. At the beginning of the games, when the other team is being introduced, we all stand and read newspapers, and then when each player's name is announced we all yell out whatever invectives we so choose. It looks really cool, a whole wall of people reading newspapers. And since there are presumably going to be a lot more of us in the section this year, it would probably work really well. Then we could use the newspaper for confetti.
I've got enough to worry about bringing in, I think all just shouting 'who cares, you suck!' works just fine
