US slang nickname for San Quentin State Prison, California — one of the most notorious maximum-security prisons in the United States. Used freely in discussions of the US prison system, in crime journalism, and in hip-hop and street culture contexts where San Quentin's reputation looms large.

He'd done five years in the Big Q and came out quieter and harder than anyone who'd known him before.
Origin: 'Big Q' as a nickname for San Quentin: 'Q' from the initial letter of Quentin, 'Big' signifying its size and notoriety. Editorial expansion authored on Slangora.
