I've always scratched my follicle challenged head at this phenomenon.

Mrs. HR and I went back to Bmore for last season Texans playoff game. There was a dude in our section with a Titans jersey on. A few folks mocked the hell out of him.

I guess people get invited to these games but are not fans of the teams playing and feel the need to represent?

Mrs HR got to go to the Texans v. Bengals wild card game and she sported her Ravens cap, telling people she was scouting for Harbaugh. That got a laugh but I would imagine she would have been mocked in her Ray Rice jersey.
