Rather than simply "water" in Japanese, this word is practicly a title given to a person who cannot create something of it's own. THis person will have to live of other's ideas (or colors, Mizu) in order to exist. This is usually a result of a
low self esteem (for
explanation, /msg Niv XD), and will usually resort in lurking, heavy-leeching, stubborn refuse to reveal details on self, etc... However, this
phenomena usually halts when reaching the age of 21, or after a 1 year period of army service.
