For the Seattle Seahawks, “12” refers to the fans — they’re called the 12s , short for the “12th man.”

Quick Scoop: What “12” Means

  • In football, there are 11 players on the field per team; “12” symbolizes the crowd as an extra player.
  • The Seahawks use “12” to honor how loud, loyal fans tilt home‑field advantage in Seattle’s favor.
  • The team retired jersey No. 12 in 1984 specifically to represent the fan base, so no player wears it now.

A Bit of History and Tradition

  • Since the 1980s, Seahawks fans have embraced the identity of the 12th man, flying “12” flags all over Seattle, especially during big games.
  • The crowd at Lumen Field is famous for extreme noise, including twice breaking the Guinness World Record for loudest crowd at a sporting event and even causing a small “Beast Quake” reading during a Marshawn Lynch touchdown in 2011.

Why It’s Still a Trending Topic

  • “12s” are regularly highlighted in NFL coverage and fan content because the Seahawks’ home atmosphere is seen as one of the toughest in the league.
  • Around playoff pushes or rivalry games, you’ll see “12” on flags, buildings, and even planes, reinforcing it as part of Seattle’s city identity, not just a team slogan.

In short, if you see a Seahawks fan say “I’m a 12,” they’re saying they’re part of that loud, proud extra player for the team.

TL;DR: “12” = Seahawks fans, the 12th man/12s, honored by the team as an extra on-field presence thanks to their noise and passion.
