I've had season tickets for 37 years. I've never, not one single time, heard that sort of thing from BYU fans, let alone entire sections. And the fact you're claiming it's on the west side where all the geezers sit makes even less believable.
Yes, surge there's a BYU fan or two that might publicly yell something like that, but not many and certainly no entire sections of blue hairs. Total fiction from you.
