I know this is a late reply but smack talking your friends is one of the best things about sports.
Like as a Nebraska football fan back when we were big 8/12 one of our main 3 rivals was Missouri. Had a friend through Xbox live that developed into a actual friendship. He was a Missouri fan every year wed make a bet on the upcoming season. There would be times we wouldn't even speak to each other during that game week and the trash taking commenced once it was over.
It's just busting balls. I remember being on my honeymoon walking the beach in Mexico with my Husker hat on when a 70 year old woman yelled at me that Nebraska sucks. She had her Oklahoma shirt on
I have plenty of hobbies and even though my team has sucked the last 25 years I still look forward to football season every year. This year my interest preseason has been at an all time low, hell for the first time in my life I didn't even know who our starting QB was up until two weeks before. But once week one hit. And Boise almost knocks of Oregon. Western Michigan basically pulled off the non upset of the year over Michigan it's back and I love it
