Vote on the prison slang that you never knew before.

"That brake fluid has been making my celly hella cranky. Wouldn't be surprised if he went dancing on the blacktop." Say what? The secret language of prisoners isn't really common knowledge for those who haven't been thrown in the slammer. If you're a fish (someone newly incarcerated), you'd better learn quickly so as to avoid a major dispute.

Cryptolects and prison code words have evolved through the ages. In the 1500s, secret prisoner languages were referred to as "thieves' cant" or "peddlers' French," but codes aren't just for prisoners: Everyone from Parisian escorts to dope peddlers to hobos has crafted their own communication methods to hide the nature of their business. 

What do prison slang words mean? Here's a handy guide in case you ever find yourself facing the long arm of the law.


  • Fish

    Fish

    Meaning: There are plenty of fish in the sea, especially in areas with rising crime rates. "Fish" refers to a brand new prisoner. A fish doesn't yet understand how to avoid stepping on their fellow convicts' toes, but they had better learn quickly.

    Use It In A Sentence: "Saw a few fish fly in on the bus this morning."

  • Celly

    Celly

    Meaning: If you were a teen girl in the early '00s, there's a pretty good chance you used some incarnation of this phrase on your AOL Instant Messenger away message, probably to the effect of "Away at the mall with Katie. Hit me on my celly!" It was the golden age of RAZR phones and cheeky nicknames. However, the phrase means something very different for prison inmates. According to those in the know, "celly" - or "cellie" - is slang for cellmate. 

    Use It In A Sentence: "My celly is my best friend; take it up with me if you have issues with him."

    Diaper Sniper

    Meaning: This slang phrase is even more grotesque than it sounds. In prison life, a diaper sniper is a child molester. According to Margot Bach, who spoke to ABC on behalf of the California Department of Corrections, taking out a diaper sniper "would gain [the killer] a lot more respect among the other inmates."

    Use It In A Sentence: "That diaper sniper is going to be dancing on the blacktop."

    Back Door Parole

    Meaning: Most people in prison are awaiting their parole, but no one wants back door parole. Why? If you're leaving through the back door, you're leaving in a casket. According to Prison Diaries, "back door parole" is slang for dying in prison.

    Use It In A Sentence: "The only way Mikey is leaving is on back door parole!"

    Permanent Pocket

    Meaning: When you're brought into a prison, your entire body is searched. This means you can't hide anything in the pocket of your jeans. Luckily enough, bodies were made with a pocket of their own: an anus. A "permanent pocket" - sometimes called a "prison pocket" - is someone's butt.

    Use It In A Sentence: "Tito stashed the dough in his permanent pocket."
