- stiff (n.)
- "corpse, dead body," 1859, slang, from stiff (adj.) which had been associated with notion of rigor mortis since c. 1200. Meaning "working man" first recorded 1930, from earlier genitive sense of "contemptible person," but sometimes merely "man, fellow" (1882). Slang meaning "something or someone bound to lose" is 1890 (originally of racehorses), from notion of "corpse."
- stiff (v.)
- late 14c., "to make stiff," from stiff (adj.). Meaning "fail to tip" is from 1939, originally among restaurant and hotel workers, probably from stiff (n.), perhaps in slang sense of "corpse" (because dead men pay no tips), or from the "contemptible person" sense. Extended by 1950 to "cheat."
