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.
