When you shush somebody while placing your middle finger on your lips instead of the traditional index finger, indicating that they should not only silence themselves, but fuck off as well. Best used against someone in mid-sentence.
Guy1- "Are you completely retar..."
Guy2-(placing middle finger on lips)- "Shhhhh"
Guy3- "oh shit, he just gave you The Rude Librarian!"
You're doing a girl in the libraryfrom behind. Her hair tied up, glasses on. Skirt long and pushed up. Right before you nut she wheals around and clamps your cock between the pages of Homer's Odyssey and you cum on her tits.
Man, I went to the library last night and the bitch by the Dewey Decimal system box made me give her The Angry Librarian. I think I nutted on the part where Odysseyus shot that cyclops dude in the eye.
