- n. a cheap lodging house
US 1904, flop + house, originally hobo slang, presumably from slang flop ("lie down to sleep"). Other speculative etymologies relate it to flopping the men out of hanging bunks by letting down the ropes. The type of cheap hotel dates to the 19th century, and was originally called a lodging house or workingmen’s hotel. (Wiktionary)
