doss
A bed — especially a cheap or makeshift one in a common lodging-house; to doss is to sleep rough.
“‘Sixpence for the doss, mate — and the straw wants turning,’ said the deputy of the lodging-house.”
Note: Recorded in Hotten's 1864 Slang Dictionary; a dossing-ken was the Victorian common lodging-house. Hotten derives it from ‘doze’.
