korean sauce
Korean sauce is a slang word meaning a "bad" pornhwa (it's not necessarily always pornhwas, sometimes it's manhwas as well). It is very similar to NTR or Netorare. It mainly implicates rape, incest, blackmail, cheating and all sorts of horrible things... It's for some reason often seen in the pornhwas nowadays (I don't know if Koreans likes this kind of thing). It's only mindless authors having nothing to do than rotting the poor souls of readers, it's the opposite of wholesome.
Scout: "Ain't liking this one, this crap is certified Korean sauce."
Reader: "Thanks a bunch! You saved me right there. Otherwise, I'd be rotting in Satan's horrible pit..."
