Book 

Means cool or awesome.

How was it Originated?

While text messaging, when you hit 2665 (trying to say cool) it will come out as book.

"Thats book, yo!"

"Book? You mean cool right?"

"Ya. LOL. thats COOL, yo."

BOOK 

a synonym of the word cool. Due to "T9" text messaging. After numerous attempts to respond with the word cool, t9 always chooses book first. Resulting in a response such as "thats book" when meaning "thats cool". It sounds good so i started to adopt it in everyday speak, and it caught fire like a dry forest in california.

"did u see rutgers comeback to beat louisville."

"YEAH MAN, THAT GAME WAS BOOK"
