It is a Japanese word meaning
cute. However, it has become known for describing a blonde white
girl who wears pink. It is used as a compliment to say how
cute they are. Other words that relate are weaboo, chuu and crybaby. People often get confused about the pronunciation. It can be pronounced two ways: the American way - ka-why, or the Japanese way - ka-why-
ee. Either way is right, but you are not truly kawaii unless you say it the Japanese way.
