What is "slam book"

n. (alternative form of slambook English)

A slam book is a notebook (commonly the spiral-bound type) which is passed among children and teenagers. The keeper of the book starts by posing a question (which may be on any subject) and the book is then passed round for each contributor to fill in their own answer to the question.

Slam books were also a source of bullying between students - where students "lived in fear" of the "biting comments" written anonymously under their names, "on the order of what today might be a Tweet or a Facebook comment".

Slam books can also exist in virtual formats. Web-based slam book sites have attracted controversy for hosting virtual slam books in which individuals or organizations are targeted for criticism that constitutes bullying or defamation.
