written documentation of the proceedings of a party. (The party's "minutes", so to speak) Mainly includes profound words of wisdom spoken under the influence of whatever legal or illegal substances are present, such as "Where'd all these robes come from?" (Natasha, 3:25 a.m., 3/22/03)
As the night progresses and people become "sketchier", the term becomes increasingly relevant to the contents of the book.
