I live just outside of Philadelphia.
Philly sports fans are fucking trash.
The angriest group of faggots you ever saw. They truly hate anyone who is a fan of one of their rivals.
You can hang out with a Giants fan, a Skins fan, even a Cowboys fan, and watch and enjoy game with them no problem.
But watch a game with an eagles fan, and be ready to be inundated with facts and figures from ten seasons ago, immature smugness when things go well for their team, and absolute nuclear petulance when things go badly. To them It's never their team that sucks, it's you, for not being a Philly fan.
