Well it's tough to spend a week or more planning exactly the right time table to get you to the zenith of drunk & stupid, then executing that plan along with pumping the precise amount of Adrenalin to generate real hate for the other team, and having it all come together at game time.
After all that prep, and being ready to kill anyone who's even courteous to the other team, to throw a minute of silence into the works, is worse than inconsiderate, it's down right mean.
