I’m not sure about it now, but at least when the Raiders were in Oakland, their fans were the definition of Psychotic. I heard one time two Raider fans were next to each other and they were both cheering and they were trying to cheer louder than the other and they started fist fighting and one killed the other. And that was a normal Sunday back in the day. These fans would get into life-threatening fights with opposing teams or each other. And they dress up like complete psychopaths with black and silver face paint and shoulder pads with spikes on them. Nobody is crazier than a Raider fan who dresses up for their games like it’s a 5th-grade Halloween costume party.
I mean these guys literally call themselves the mafia, what is crazier than that? These guys jump through tables, tap kegs, and set themselves on fire just for the pre-game. These fans have been through a lot too. They make it to the playoffs every year and their team fumbles the bag every damn time. If the Bills were to somehow win the Super Bowl soon, Bills Mafia would treat Buffalo like one of their folding tables at a family BBQ and break it in half.
Any Philadelphia team-
If you live in Philadelphia, you must be clinically insane. These fans are a different breed of humans. Philly fans are more passionate about their sports teams than they are their own families and friends. They even love a fictional boxer more than their own damn dog who probably shares the same name as him. As crazy as they are, you do really need to check in on them. After losing in both the World Series and the Super Bowl, Philly fans are at wits end and are on the brink of burning down the city.
