Aris flew into a hotdog fueled rage after his attacks were thwarted by a masterful dance of korean backdashes.
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.

Reader: "Thanks a bunch! You saved me right there. Otherwise, I'd be rotting in Satan's horrible pit..."

Theresa is Korean two-faced, she has such a great smile when you talk to her. Only because she will have something to say when you walk away.
