Having bad fortune, experiencing a misfortune, as in You're out of luck if you want a copy; we just sold the last one. This expression, first recorded in 1867, assumes that good fortune is a finite quantity that one can run out of. However, it generally applies to more temporary circumstances than being DOWN ON ONE'S LUCK.
