In terms, it means having a thread moved to the Chatterbox forum due to it either being spam or low-content in the previous forum, according to the stickied rules and Moderator decision. Users do a number of things to prevent their topics from being sent to the Chatterbox. They either try to flesh out the purpose of their topic and leave an open discussion so others can expand on it, or they give a little rule in the opening post that tells others to stay on topic.
