I knew a fair number of Ohio State fans back in the day, they were all quite reasonable. Small slice of course. I've never met a "terrible fan" of CFB, met a couple on line if you call it meeting.
We used to have a "fake?" Tennessee fan here who always predicted 12-0 seasons and gave ridiculous excuses or disappeared for the season when they lost. He was ... amusing at first, then predictable and not funny.
