Uhmm, no... Omaha is a chant used by the Seahawks. I'm originally from Seattle, Washington. Seahawks are my home team!
Guys, it's not a chant....it's a signal to Peyton Manning's offense that depending on the signals given previously is either used to trick the defense or signal a certain play. It might also be a chant from Seattle, but in this situation Omaha is talking about the signal you hear Manning yell at the line of scrimmage frequently. Omaha Steaks tried to pay Manning to use it at least once in the AFC Championship game for some weird twisted advertising, but he turned them down. That's why it's been being talked about recently.
