I stressed that it’s fine to use these new baffling words in Korean, but it sounds like bewildering nonsense to English speakers and if the coinage is English-based and really outlandish, it can communicate an unintended meaning to an English speaker. They were surprised to learn these neologisms aren’t in wide use in the English-speaking world… because are always being presented in roman letters, to lend them greater credibility and “flair”.

(Which is why EFL instructors especially hate these clunky, dumb neologisms.)
