I really should watch more TV. Apparently there has been a sci-fi series called “Firefly,” concerning which a couple of readers have informed me thus:

“Derb—Actually, ‘Chinese’ is already seeping into our slang in one place – the science fiction universe of Firefly. In the one season of episodes and in the movie, a slang is used that is based partly (and probably very loosely) on Mandarin. A few examples (without all the little marks that would make these look right and be pronouncable):
dong ma – understand?
mei mei – little sister (literally or figuratively)
tsai boo shr – no way!
choo fay woh suh luh – over my dead body
huh choo-shung tza-jiao duh tzang-huo! – filthy fornicators of livestock!
kan woh-mun tzun muh suh bah! – let’s watch how we die!
“Evidently some fans of the series/movie have taken to this form of expletive expression with a vengeance….”

[Derb] Readers of Fire from the Sun, Chapter 51, will be aware that those who want to import Chinese slang into English should be careful what they wish for.
