Seattle Seahawks fans are called the "12s" because the team honors them as the "12th Man" (or player) on the field, with the nickname evolving to "12s" to sidestep a trademark dispute. This tradition highlights how their raucous noise at Lumen Field (formerly CenturyLink Field) rattles opponents, causing false starts and disrupting plays.

Origin Story

The nickname kicked off in 1984 when the Seahawks retired jersey number 12 solely for their fans, symbolizing their game-changing energy—no player could wear it again. Picture this: Before every home game, a giant "12" flag rises above the stadium, whipping the crowd into a frenzy that engineers even designed the venue to amplify. Back in the day, fans like "Bill the Beer Man" and "Mama Blue" embodied this spirit, turning Seahawks games into legendary events.

Why "12s" Instead of "12th Man"?

Texas A&M University trademarked "12th Man" in the 1990s (stemming from a 1922 story of a fan subbing in during a game), licensing it to Seattle until 2016. Rather than renew amid tensions, the Seahawks rebranded to "12s" , keeping the vibe alive without legal hassle—fans embraced it as their unique identity. Forums buzz with pride: One Seahawks.net thread rallies the "12s" to outdo rivals like Kansas City in noise records.
