With Seattle Seahawks fever reaching extreme levels as the Super Bowl nears, perhaps it was only a matter of time before it gripped new parents looking for baby names.

A Washington state couple with the last name "Mann" has named their infant daughter Cydnee Leigh 12th in honor of their hometown team and its vocal supporters.

That's right, “12th” is her real middle name, and when paired with her last name, it sounds like “The 12th Man,” which collectively refers to Seattle Seahawks fans. They “are known as the loudest in the NFL… giving the Seahawks a home field advantage,” the football team proudly declares on its website.

Proud papa Troy Mann told TODAY he’s been a Seahawks fan for more than 20 years. The Port Angeles, Wash., family was watching the Seahawks-49ers game on Jan. 19, he said, when the baby started kicking his pregnant wife’s belly like never before. Soon after, the hometown team came from behind to secure the nail-biter victory that landed them in this Sunday’s Super Bowl.

“She’s never kicked for that long, she’s never kicked that hard, and I told my wife, ‘See, it’ s a sign,’” Mann said.

Cydnee Leigh 12th Mann was born Monday, Jan. 27, at 9:41 a.m. at Seattle's Swedish Medical CenterToday

Kelly Mann, who gave birth to the girl on Monday, says her older children are already jealous of their sister’s unusual moniker.

“We have two other kids at home who are 10 and 6, so now they want ‘12th’ as their middle name, too,” the Port Angeles, Wash. mom told NBC News affiliate KING 5, laughing.

Mann and her husband showed off little Cydnee Leigh 12th already dressed in Seahawks gear. The new mom, also sporting a Seahawks T-shirt, called her “our little Sea Gal,” the name of the Seahawks cheerleaders.

Both mom and baby returned home to Port Angeles on Wednesday. They plan to watch the game Sunday from their home. 

But her grandparents might have to wait until after the Big Game to come for a visit. 

“Her grandpa in Colorado is a Broncos fan,” Mann said. “As soon as she was born, they said, 'OK, we’ll send her a little Broncos hat.'” 

They're not the first parents to find name inspiration in sports. Last fall, a Wisconsin couple named their baby after Green Bay Packers quarterback Aaron Rodgers, because both had broken collarbones.

And in December, an Alabama couple named their son Krimson Tyde in honor of the University of Alabama's football team, the Crimson Tide.
