We often hear from pen-pals asking the meaning of certain words or phrases used by inmates. Prison is a culture all its own, and vocabulary moves toward slang upon prison entry. Many inmates come from lives on the streets, and this can produce a heavy use of slang; other terms are prison-based in their origin. We have put this section together to help the public understand the meanings behind some of these terms. Some of our information comes directly from prisoners and officers. Please note: This section may be offensive to some; however, it is designed to be complete, not polite.
