Vikings fans are the little boy who cried wolf. They can dish it, but cant take it. When I was at the super bowl, a vikings fan in full vikings gear was in the front of our section and was antagonizing eagles fans and clapping in faces and talking a lot of shit every time the patriots did something.
In the 2nd quarter, a woman (A HERO), threw his vikings hat/helmet off the balcony. Within minutes he flagged security and got her kicked out OF THE FRIGGIN SUPERBOWL! What a loser.
Quick story: When I was 17, me and a buddy drove up to Giants stadium for the playoff game (want to say it was 09?) We were sitting in the upper levels, and we were pretty good about not talking shit and respecting that we were visitors of a rival team. When Brandon Jacobs got stopped on 4th and 1 to basically end the game, I stood up and clapped....and immediately was punched in the face by what had to have been a 40+ year old man lol. It was one of those moments when time stopped. We had even been talking to this guy and his 2 brothers next to him for the entire game. Was a heat of the moment event, and I wasnt even mad because I was thinking to myself "what if I was a giants fan and stood up and clapped in front of a dejected fanbase that just had their hearts ripped out in the playoffs by a rival team" and realized the same result would probably occur in philly. Almost every giant fan around me just sat there stunned. Even though I was 17, I am 6'5 so easy to think I was older. We took that as our time to leave (whole stadium was emptying out at this point) and proceeded to dodge beers and insults on the way out. I was soaked with beer by the time I got to the parking lot. Once again, I am not completely innocent as I definitely stood up with an obnoxious clap when that happened, but that was a lesson I learned at an early age.
Edit:
@WIP CALLER , you are 100% correct.
If you sit in the upper levels in any rival stadium, you are doubling your chances of having a bad time. I understand that financially not everyone can afford to sit in the lower levels, but if a concern of yours is how the opposing fan base will treat you, it is absolutely worth the extra money. Once again, drunken idiots are not unique to Philadelphia nor are assholes.
