KY - a Japanese buzzword.

KY (pronounced as "Key-why") is one of japanese buzzwords of 2007.
It's the abbreviation of Kuuki(atmosphere) Yomenai(can't/don't read), and literary translated as "someone who can't/don't read the atmosphere"="someone who acts improperly".

For example, you can use it like this "He was making silly jokes during the whole meeting with our professor yesterday. He was so KY!" Got it?

In Japan, it is really important to read the atmosphere and read other's thoughts too.
We think we can/have to tell each other's feelings without saying a word.
I think that's the reason why some Japanese are poor at asserting ourselves.
People from foreign countries may think it's so confusing, but I'm used to it and like this Japanese style of communication.
Here is a Japanese saying "Say one, know ten" .

Actually i don't use KY much, but high school students and junior hugh school students use it a lot!
I feel old and the generation gap :'(
