This sounds like a battle cry for Kansas City Chiefs fans.
Local fans have claimed that Arrowhead Stadium is the loudest stadium in the NFL for years. However, the Seattle Seahawks officially have that honor.
The fan group attempting to set a Guinness World Records mark for loudest stadium says it has established a record during Sunday night's game between the Seahawks and San Francisco 49ers.
The group, called Volume 12, announced on its Facebook page it had set the mark late in the first quarter. The decibel reading taken during a sack of San Francisco quarterback Colin Kaepernick in the first quarter — following a one-hour weather delay — was 131.9 decibels.
According to a Guinness World Records, that record was then apparently broken again midway through the third quarter when the noise reached 136.6 decibels.
The previous record for "loudest crowd roar at a sports stadium," was 131.76 decibels, set in 2011 in Turkey at the Ali Sami Yen Sport Complex Turk Telekom Arena during a soccer match between Galatasaray SC and Fenerbahce.
The group footed the bill for the Guinness World Records official to come to Seattle and wasn't affiliated with the team.
However, Chiefs fans plan to claim that record for their own.
Reports say they will try to roar their way into the record books during the Oct. 13 game against the Oakland Raiders.
