1. A stroke of astonishing luck that comes out of no where!
2. A very bad luck incident near the end of a string of bad luck that seems to never go away.
1. Person scratches off lottery ticket. "Fuck luck! I just won the damn lottery!"
2. Person has a car wreck after leaving late and spilling coffee on themselves. "Fuck luck! Can it get any fucking worse!!"

Another way of saying hell or fuck.
