Go here and record a chant that's going to be used in the movie.

from ign.com:

 

Back at the 2010 San Diego Comic-Con, Tron: Legacy director Joseph Kosinski provided a unique opportunity for all those in attendance at their panel. With an extensive series of scattered microphones, the audience was able to record a track of chanted phrases that were later incorporated into the Game Grid sequence of the finished film. Now, in 2011, The Dark Knight Rises composer Hans Zimmer is looking to pull off a similar stunt. But this time, you can participate in your own home.

Hollywood.com reports that through the use of ujam.com, you can record your own voice uttering the simple chant, "Deh-shay bah-sah-rah mean!" (Don't ask us!), and it will be incorporated into the final cut of the film! Here's what Zimmer has to say on the experiment:

"We need to hear your voices! Now and Loud! We are creating the sound of a worldwide chant. Everyone come and be part of it. It's easy: There is no such thing as out-of-tune, no timing we can't fix later. If you mumble, growl, scream or whisper, it's all good. Make it yours. If you only get halfway through, no problem! Do it alone, bring your friends, but do it with energy and commitment. Let your voice be heard and be a part of our adventure!"

Pretty cool, right? So, if you want to be forever immortalized in the third installment of the coveted Bat-trilogy, then head on over to ujam and let your voice be heard!

it's just a small chant but still kind of cool to know your voice will be in that movie forever in some form, kind of like being an extra in the back of a big crowd scene.
