Those who've read Harry Potter
Another knock-out crappy thread this.
Something reminded me the other day of the character of Tonks. In the books she says 'wotcha'. I don't think I've heard anyone use that word since the mid-80s and it made me think (at the time) that Rowling hadn't spoken to many teenagers of late.
But maybe I'm wrong. Maybe it's massively popular.
Wotcha!
