A librarian, primarily in middle and high schools, who believes that their power to hush restless students is much more important than it actually is. They hold their power to quiet people on command up on a pedestal, for it is the only power that they possess. Rule enforcement is their primary goal, above education.
That librarian gave me a detention for asking my friend if I could borrow a pencil, she must have Vigilante Librarian Syndrome.
I was in the library talking on the phone for three seconds and was hushed violently four times. This over-stressed college student I know must have Vigilante Librarian Syndrome.
