I came up with it while watching a Rider home game this year. You never see fans from other teams at Mosaic. Seems to me as that would be very boring with just green and white and no other fans to get chirping at.
Had my faith in some Rider fans still being solid cool fans when I met about 10 very cool fans at the Argo Bash on Friday at Grey Cup. Normal cool fans. I'm so used to the newer Rider fans who get all hopped up on PIL and act like a pack of fools.
