What is considered a “college town”?

[Thank you for being a friend...]

I grew up in a town with a college in it but I would not call it a college town the way State College (Penn State) is.

I guess college town conjures up images of a lot of young people hitting up bars at night, getting drunk, lots of fraternities and sororities, lefty faculty members, general debauchery like underwear runs at midnight, maybe a few coffeehouses where there is always a kid in a goatee talking about Karl Marx to a bunch of drowsy friends who are checking their iPhones, and a conservative in the corner reading Ayn Rand, that kind of thing.  It's very cliche.
