A new bit of Korean youth slang: "뭥미?" (mweong-mi? said in a kind of dumb rising tone). It means something like "what the?" (as in "what the hell?") although you won't find it in a dictionary. When I say it in the right situation to one of my classes, everyone collapses in riotous laughter. But when I tried it out on Curt (my boss), he said "is that Korean?" Generation gap, y'know?
