Philadelphia Eagles fans are on a different level compared to most NFL fanbases.
The passionate intensity of Eagles supporters and a growing rivalry with the San Francisco 49ers was incredibly evident before last season's NFC Championship game between the teams.
It also surrounded Joey Bosa, who officially plays linebacker for the Los Angeles Chargers but was wearing a 49ers jacket while supporting his brother, Nick, on the road.
"Bosa!" yelled an Eagles fan as Bosa approached the stadium turnstiles.
"Bosa sucks!" screamed another fan, while Joey casually hung out near an entrance to Lincoln Financial Field on January 29.
"When do the Chargers play this week?" a fan asked.

It was a trick question, since Los Angeles had already been eliminated from the playoffs.
The warm back-and-forth picked up from there, with Joey approaching the screaming fans and asking one if he was "Snapchatting your little little butt buddies, you f****** loser?"
The Chargers defender cracked a smile, briefly seeming to enjoy the real-life interaction with Eagles fans.
But the Philly screaming only continued and Joey eventually tired of the teasing.

When a fan yelled out asking how Joey's penalty fines were, the four-time Pro Bowler fired back again.
"They're fine, because I can afford them," the Charger said.
Joey was pulled into the entrance by nearby supporters.
But the NFL star got in one more one-liner before strolling into the stadium.
"I'm f****** rich, you broke b****," Joey said.
The Eagles and their cheery fans got in the final word on that day.
San Francisco quarterback Brock Purdy was knocked out of the NFC Championship game early and Philly won 31-7 in a blowout.
At least Nick's brother didn't have to pay to watch the 49ers lose.
