tre book

Tre: derived from the french word tres meaning (and substituted for) the word 'very'. Except, in this context it is written phonetically and you leave out the s. (The irony makes it hip) Book: derived from t9 predictive texting. When attempting to type the word 'cool' but t9 recognizes it as 'book'. People got lazy (people in Davis, Ca, to be exact) and left it as is, substituting 'book' for 'cool' in texts. trend eventually spread to spoken word. -Often (but not exclusively) used sarcastically when apathetically humoring another person, but really the person doesn't give a shit. *not to be confused with, and not in association with Green Day's drummer Tre Cool*
