The burn book is usually created by the popular clique in school, roasting and gossiping (mostly) about everyone that gets in their way. But it can also talk about some new, hot guys at school, juicy stories, and all those fugly sluts there is today. Here's a tip: DON'T trust anyone with your secrets, and you most likely won't get in the Burn Book history. (SAYS NO ONE)
the Burn Book is made up of everyone in the school, saying nasty things about everyone's private life.

A book which contains bitchy comments about other people, often friends, school mates, etc.
Person 1: OMG! Shes such a bitch, i can't believe she slept with my exboyfriend, what a slut!

A site which contains bitchy comments about other people, including but not limited to friends, peers, celebrities, politicians, etc. An online burnbook as the name references does not need to be a physical book but can be a website such as burnbook.com.
In an online burn book I was called me a stupid whore who sleeps with anything and everything, regardless of sex or species and dead or alive.
