Nac 

Prison/jail slang for a lame, on the lower end of the institutionalized social food chain. No game, no hustle, often feeding off of the feats, misdeeds and/or criminal accompliments of those more recognized. May be caught "borrowing" the tales or stories of more infamous comrades. NAC is literally an acronym for Not A Claimer

David is a fuckn Nac; he claims he's doing 10 years for possession, sales and mayhem buts he's really here on Illegal Lodging.

NAC 

Not a convict,
New age inmates that don't follow the prison code.
People that are more along the lines of being a tool bag and running risk of getting beat up in prison due to immaturity.

Don't listen to that NAC.
