You forgot ‘Plainsmen’ for Auburn and ‘Engineers’ for Georgia Tech. Virginia Tech has ‘Hokies’ and ‘Gobblers’, but they are trying to forget the latter. As for Virginia, the word on Vinegar Hill is that a ‘Wahoo’ is a fish that drinks a lot.
And as the father of a UVA graduate, yes, the wahoo is a allegedly a fish that can inhale large amounts of water to make itself larger and scare off predators. It's ability to 'drink' so much gives way to UVA nickname of Wahoos.
Most of my money went to pay tuition, but some it went towards a "Hoos" t-shirt.
As for Harvard's Crimson and the Johns, I swear there was a third name for the Athletic teams - but it's been a long time since I was a student, and I can't remember the other name, if, in fact, it existed.
