The one that was a senior when I was a junior, wore a t-shirt sometimes that said f:
And then a list of things related to BYU. And then finished with f BYU.

My school definitely would have chanted it if they were allowed. To be honest, I was confused as to why he didn't like byu. And I was surprised that his dad who was my little league basketball coach let him wear it. And I was surprised that he was pretty cool with me even though he knew I was LDS and a huge BYU fan. I told him his shirt was stupid but didn't take it too far cuz he definitely had most of the clout on the team, was kind of intimidating to me because he was held back and actually two years older than me, etc.

I laughed when he took a scholarship to Idaho state and ended up in a state and on a campus with a lot of members lol.
