A book or collection of papers used by graffiti artists to paractice writing. Usually a black hardcover book with blank pages but can just be a notebook or collection of papers.

A magazine aimed at the sophistcate hipsters, the posh anti-socials and the artsie farts of the city. Self described as "The International reference for fashion, beauty, photography, luxury advertising, graphic design, production and events." the magazine is blissfully aware of the irony they represent by condensing the world of alternative culture into one magazine (although it is quite thick.)
Sweet! I just got my new issue of blackbook, the Arts Issue, with profiles on up and coming artists, a photoshoot spread of a preggers Maggie Gyllenhaal, and so much more!

Any scandalious event (usually sexual in nature) that involves money, fame, bribes, or fortunes that may be used for monetarial purposes in the future. These events are logged in a "black book" or journal. When you feel threatened, gently remind that person on your list that you have "blackbookable" material on them.
"Thelma and Louise were best friends and knew everything about each other, keeping a detailed journal of all of their "blackbookable" moments they shared."

"Monica Lewinksy's dress was evidence for her "blackbookable" moment with the president!"
