When I was in college, I had no qualms fanning the flames of Bedlam. Talking to anyone wearing red, I would unequivocally tell them how badly I imagined the Cowboys were going to mop the floor with OU. That probably had a lot to do with immaturity. It also might have been influenced by John Blake being the Sooner football coach.
Soon after I graduated, I was still pretty obnoxious. With Les Miles helming the team, he gave the players--as well as the fans--a swagger that made us feel it was the Sooners who were the underdog in the fight. He did things like not talk trash by not forfeiting the game before the mighty Sooners fielded the kickoff (the infamous "so we're told" press conference). He said things like "Let 'er rip" to sideline reporters. Most importantly, he beat OU.
Now that I'm in my 30's, and Mike Gundy only intimidates female sports reporters, my trash talk has dwindled significantly. I say things like, "we'll see if the team can take care of business," or "If the defense can get some pressure on Landry, we have a chance." Suck on that Sooners!
