Book Text Is Cool
On a recent TV show, British actor Stephen Fry discussed how his nephew replied Book! when the actor gave him a PSP as a present. Book means cool. It comes from text messaging culture. When you type with predictive text on your mobile phone the word cool the word book first appears. Users should then flick through the list of possible words to get to cool. British youth appears to be avoiding the additional keystrokes and using the word book instead.
