is a common practice (often found on board naval submarines) where several people share the same bed. When the next person swaps out for work, the person laying down finds that the bed is still warm from the prior user, hence the term hot bunking.

Term derived from the US Navy. When three sailors that work different shifts are required share a bed, each getting its use for an eight hour shift. Thus the bed (bunk) is always in use, always warm. i.e. hot bunk.

Term also describes the situation when a man-whore is bedding multiple women at times that nearly overlap. Thus the bed is in constant use and always warm. i.e hot bunk.
