4. If you start spouting off rules for what it means to be a "true" fan, then you're kind of a glutealcranium (no offense intended).

I've butted heads with and disagreed with tons of people on here over the years when it comes to BYU football, it doesn't mean I think they're any less of a fan. However, when people start blah-blahing about "true fan" garbage, I know it's time to tune them out.
