What about naming a specific university of college?
I would say specific for everything except for names of people. The names of colleges, universities, frats, and organizations are all on your application anyway.
In my personal statement, I mentioned the name of my professor that I did research with. Now that I think about it, it's probably not the best idea. At the same time, they have that information in my application anyway that I don't think it makes a whole lot of difference. But I would steer away from names of coworkers, customers, clients, etc. You get the idea.
