Rookie Dude,
Where I grew up, that term was used for meaningless and unimportant. Thus the confusion.
I have worked games between undefeated cross-town rivals in front of standing room only crowds. Also worked those YMCA games for 3rd graders. Believe it or not, I approached them and prepared for them exactly the same way. I can also honestly say that my adrenaline level was the same for both games. Maybe it is because I have a high-pressure real job, but knowing it is a "big-game" and seeing a large crowd didn't phase me. And in both cases I didn't even hear the crowd.
My wife keeps telling me I'm weird and different...maybe she is right (don't tell her I said that

)
