Bates students (Batesie or Bobcats, occasionally just ‘cats) are “60 percenters” if they marry another Bates grad, based on the apocryphal statistic that 60% of Bates grads marry another Batesie. In reality it’s more like 14%, but that’s high enough that most Bates grads know a few people who have married fellow alums. “ I see your husband/wife is wearing a Bates shirt. Are you a 60 percenter?”
“There is such a thing as a Smithie, and there used to be Cliffies.”
My daughter reports that there are still one or two old professors at Harvard that still refer to female students as Cliffies.
“I’m guessing the rest of Ivies:
Harvard = Harvardian
Princeton = Princetonian?
Brown = Brunonian
Dartmouth = Dartie?
Penn = Quaker?
Columbia = Columbian?”
I was tongue-in-cheek about the ones in question marks but I’ve seen in Brown threads someone reference Brown students as Brunonians, I have heard the term Harvardian. @skieurope l hear you on post #25, I wouldn’t reference that term either if I were a Harvard alum…sounds too much like a certain cheese 
" The singing group “The Cliffe Notes” called themselves that because they lived in the Radcliffe dorms, not because they were women."
The 'Cliffe Notes, then and now, are a subset of the Radcliffe Choral Society, so that’s where the name came from.
Nope, not the year they were founded. It was a four person a capella group all of whom lived in South House. Maybe the Racliffe Choral Society stole the name after they graduated.
I’m a Bobcat.
My DH and both kids are “graduates of Blank University”. Fill in the blank with the name of their colleges.
Williams College grads might refer to one another as Ephs (for Ephraim Williams and the nickname for the sports teams and the start of the name of various student groups like the a cappella group Ephflats). But in the world at large, we are lucky if the person we are talking to knows the name Williams, never mind Ephs!!!
D is a grad of Earlham College, and they refer to themselves as “Earlhamites.” The sports teams are known as the Hustlin’ Quakers (used to be the Fighting Quakers, but that somehow seemed wrong), but sports don’t have a large presence there so the name doesn’t carry over.
The term Princetonian does get used, if not by alumni or current students. I recall that the Princeton administration keeps a file of people claiming to have degrees from Princeton of which the school can find no record. The file is called “Doubtful Princetonians.”
Are Franklin & Marshall students really called “Dips,” short for Diplomats? I seem to remember that from the tour.
Be a Buff. Or a Forever Buff.
Women who reply that they went to college “in New Jersey” when asked are Princetoniennes. But that’s used only when referring to other alumnae - not as a self-identifier. The male type are Princetonians. Either gender can also be referred to as Tigers. Children of alumni are tiger cubs.
The name for sports teams at the University of Alaska Fairbanks is Nanooks, which is the Inuit name for polar bear. I wish I could say students called themselves Nookies, but alas, I can’t.

Yaliens.
If you went to Colgate, you could call yourself a Raider - was once “Red” Raider - but I don’t think anyone does, unless they played sports, particularly football. Raider Football is a thing. (The were once pretty good, before dropping down to the Patriot League)
About Raider Football, it is a “thing” that many alumni support readily. Colgate was co-winner of the Patriot League l title last fall with Lehigh and was a charter member of the league founded 31 years ago. Lots to be proud of with 8 league titles and post-season games including the national championship in 2003, a loss to Delaware. So nothing to sniff at. See you at Andy Kerr Stadium this September 23 for Homecoming versus Lafayette which also commemorates Colgate’s bicentennial year.
Go ‘gate!

Mainers?
There aren’t very many of us as St. Lawrence is pretty small, but we are called Larries. Larries are a pretty proud group (always wearing school t-shitrs, hats, car bumper stickers…) and we seem to find people wherever we go. My good friend who did not go to SLY but hung out with a big SLU crowd once said, “For a small school you sure have a lot of alumni!”
