An anacronym that stands for a group of people. Said group of people resides in Harford County Maryland. They are known either as Constant Blunt Smokers or Casual Bowl Smokers. The former being the harder core version.

In addition to Casual Bowl Smoker and Constant Blunt Smoker, CBS has several cover anacronyms used as explanations for rampant notebook-graffiti. Some of these include:
