To get someone's number
I want to go book some boys at the mall today. I booked some boys when we went to Six Flags last week.

Synonymous with "cool." Used only by really hip people between the ages of 18-25.
You look so book with that backpack.

Book is another word for 'COASTER'
You use books to make sure that when you place your cup on a wooden surface, you don't ruin the wooden surface.
Joe: Yo Mark, can I leave my cup on your beautiful wooden table?
Mark: Yeah, but use a book!! I don't want you runing my table!! It's beautiful!!

A blank notebook shared between best friends or an amoeba. The friends take turns adding entries pertaining to life, boys, sex, school and the idiots that make up half of our population. The Book is treasured by the friends and can be seen only by their eyes. It is exchanged between it's owners at candlelit vigils.
1) The amoeba has a Book.
2) One day those girls will publish The Book.

An alternate word for "cool" that requires two less keystrokes.
-"Dude, that tie is book!"
-"Thanks man. Stay book."

The word that shows up in a text when the texter, using T9, attempts to write "cool" but fails to press shift.
You: "I'm coming by your place later"
Them: "Okay. Book"
Them: "Oops I mean cool"

A movie that hasn't yet been shot.

(Also, of course, T9's subliminal message that's supposed to make you think that books are actually cool. Because book comes before cool. Yeah. Right.)
