Is Snaffle taking it personal or just because he is like that?
Anywhay, what are blackbooks?
Good ole' Snaffy is just the argumentative type.
A blackbook is a graffiti artist's drawing board, the place where they first draw a potential piece. They draw up a preliminary sketch in the book, colour it until they find it sutable, then actually go spray it after that. Good artists don't just throw pieces onto the wall, they plan them out like true works of art. Unless you just plan to tag stuff, in which case you just need to make up an interesting name for yourself.
