Feminine form of Narcissus, ultimately derived from Greek and possibly meaning "numb and sleepy". Narcissus was a hunter in Greek mythology who was known for his beauty and was extremely proud of it. As a punishment for his pride, he was lured to a pool to see his own reflections. As he fell in love with it, he was not able to leave the pool and died. Later on, the term 'narcissism or narcissistic' started to be used to express overt self-importance or vanity.
