A flophouse was a place that offered very cheap lodging, generally by providing only minimal services. The term "flop" was part of vernacular of the 1930s United States of America on Earth. Captain Kirk was momentarily perplexed by Edith Keeler's use of the term "flop" during his visit to that era. (TOS: "The City on the Edge of Forever" ) In 2374, The Doctor sarcastically commented that Neelix was trying to turn sickbay into a flophouse when he and other USS Voyager crewmembers began living there during a fuel shortage.
