Colin, I made it up just to annoy you.
Steeler fans have been called "Steeler nation" for as long as I can remember. Could have something to do with the fact that every game they play is sell out no matter whether it's a home or road game. The NO game there were 10,000 tickets available the week before the game. Thanks to Steeler nation it was a sellout. A lot of fans get to see their teams on tv thanks to Steeler nation.
I am a proud member of Steeler nation and don't take kindly to Florida wussy boys dissing us. As America's favorite redneck Charlie Daniels once said, "Just go and lay your hands on a Pittsburgh Steeler fan and I think you're finally gonna understand..."
