All of our chants and cheers were made up in 1894. Even the ones that we just started doing in the last few years and even the ones that specifically reference bulldogs. We have a whole book of cheers that we wrote back in the day and we even shared them with other schools. If we use it, then we were the originators and anyone else that uses it just copied it from us.
I have all of the paperwork if anyone would like to see it.
