There are plenty of resources online where you can learn “regular” Japanese, so here I decided to let you know about words and phrases that I learned not from any textbook, but during conversations with native Japanese speakers.
“KY” is one of the very first “slang” words that I learned not too long after coming to Japan. It’s used as a derogatory term for someone who either never has anything of substance to talk about or drastically interrupts the flow of a previously interesting conversation. One thing it isn’t however is a secret. Usually it will be said by someone straight to the person’s face as soon as they say something stupid, and it almost always ends up with everyone else in the conversation agreeing. However, it’s not of course a terribly offensive or irritating thing to be called when you’re with friends. Since I haven’t heard too many adults say this word, I’d assume that it’s more reserved for the teen to 20-something set.

The acronym itself stands for “Kuki Yomenai (空気よめない).” The characters roughly mean “sky” and “spirt,” with the idea behind the meaning being that the person is so dumb that they can’t read the current situtation or conversation. As an English speaker I of course took a minute to make the distinction between this and the famous lubricant of the same name but that went away fairly quickly.
