Cydnee Leigh 12th Mann: Seattle Seahawks parents name newborn after nickname given to fans

SEATTLE -- A pair of Seattle football fans have bestowed quite the name on their newborn: 12th Mann!

12th man is a nickname for fans in the stadium during games.

The baby's legal name is Cydnee Leigh 12th Mann.

Now the proud parents say their other children are jealous. "We have two other kids at home that are 10 and six and now they want 12th as their middle name too," Cydnee's mother said.

Cydnee's parents say they made the final decision about her name during the NFC Championship Game.

They announced their name choice on Facebook... but didn't realize how much attention it would generate.
