prison wife
n.— «Fraudsters don’t do well in prison…They are the lowest of the low. They are considered snitches; they are dishonest; they can’t be trusted. That’s why they end up in the prison wives’ club.» —“Meet the leader of the fraud squad” by Bernard J. Wolfson Orange County Register (California) Mar. 29, 2005. (source: Double-Tongued Dictionary)
