hot bed
v. phr.— «While prisoners are out, their cells will be given to other inmates in what is called “hot bedding.” That will allow prison bosses to increase the total number of inmates in the country’s two open prisons from the current 400 to around 475, taking pressure off other overcrowded prisons such as Barlinnie, Greenock, Aberdeen and Inverness.» —“Prisons chief fears ‘week-at-home’ scheme will increase reoffending” by Michael Howie Scotsman (Glasgow, Scotland) May 6, 2006.
