Japanese to English Art/Literary Poetry & Literature novel

This is slang. I assume it is a play on words meaning "fucked"? Fuku in Japanese means many things, one of them is "luck" from what I found out, but I don't speak Japanese and need to translate the term into Spanish!

The whole sentence is "If he's said no, nigger would probably still be OK. (If you call being fuku-ed, being beyond misery OK.)

Any feedback on what the term could mean in English?

Thanks!
