What are some real life prison nicknames?

Answer 1

"Puppet" is one.. very dangerous nickname, it means someone who is totally willing to do whatever they're commanded by a "higher up"

"Countess" is a real nickname of a man living in prison as a woman

"Timber" was also a man who lived in prison as a woman

Real prison nicknames are hard to find unless you know someone who's really been in the system. It's not something they often discuss openly with outsiders. ---- Off the top of my head, I remember "Issues", "Rhino", "Mad Dog", "Maddness", and "Body bag".
