During the second quarter of tonight’s Monday Night Football game, Kansas City Chiefs fans set a new Guinness World Record and helped make Arrowhead Stadium “the loudest stadium in the world.”

For those that haven’t kept up, this is a recent new trend for NFL teams — well, at least two of them.

About one year ago, Seattle Seahawks fans broke a two-year-old crowd noise record at CenturyLink Field — which was specifically built to increase noise levels — in a game against the 49ers at 136.6 decibles.

Then, the Chiefs wanted in on the fun and fans at Arrowhead Stadium set a new world record one month later, beating Seattle’s mark by 0.9 decibels.

But the Seahawks wanted the record back and the 12th Man came through this past December with a noise level of 137.6 decibels, narrowly beating the Chiefs record.

Apparently the Chiefs organization didn’t want to let Seattle be both world champions AND the world-record holder for crowd noise level. So, today, fans got real loud — like, 142.2 decibels loud.

Fans in Kansas City were pretty amped about it (notice the excellent observation from @DaynaOG):

it’s unclear if the Seahawks will try to take the record back. For now, the team appears to be pretty friendly about the competition:
