He sings about the Seahawks. He posts skits about the team's biggest rivalries. And in the stands, nobody cheers louder.
He is Norbert Caoili, the multi-talented host of his own YouTube channel Norb Cam.
"I like to have fun," says Caoli, who along with his dad "Kuya" Bert, has been a season ticket holder for nearly 20 years.
"There's a lot of fans that don't get to go the game for obvious reasons," says Caoli. "I'm one of the lucky fans who do."
Last season Caoli was lucky enough to go to the biggest game of them all. He documented his trip to the Super Bowl in an hour long video that had the happiest ending imaginable.
"Go Hawks! Let's do it again next year, huh? Let's do it again!," he's seen yelling into the camera.
"It makes me feel good knowing people around the world, around the country, are enjoying the experience with me," says Caoli.
That's why he's expanded his offerings. A co-owner of his own video game production company, Caoli has been making more polished videos.
"I decided I needed to do more to fill the fans need for Seahawk excitement between Sundays and on the off season," says Caolil, "so I started doing these videos called "Rivals" where it's me battling it out with another rival fan from a team that we're playing that week."
The fight scenes are intricately choreographed but you can guess who always wins.
"It just fuels the fire and gets everybody revved up for the next game," says Caoli, a true super fan who is celebrating the home team like no one else.
"I'm a fan first," says Caoli, "so I just want to keep doing what I can to help fuel the Twelves."
