1. n. & adj. Haruhi can be described as a state of being, in which you feel as if you're just one in a million. Although you may feel as if you are an individual/one of a kind, you are incorrect. Their maybe thousands of other people that have your personality, look like you, dress like you, have the same friends like you, have the same secrets as you, have the same dreams and wishes as you. Haruhi is a state in which you feel that you're alone in a world that is dull and boring and repetitive. This state can only be cured by overloading your life with extreme happiness and being random and eccentric so that hopefully you'll truly be "one of a kind". Amazing things happen all the time, you just have to find it.
