contempt, insult

嫚 is composed of 女 (woman) and 曼 (gaze far, extend). 曼 originally means gazing far into the distance. Looking away during a conversation is a sign of disdain or insult toward the other party. In ancient times, women held a low status, and many derogatory Chinese characters included 女 as a component. Thus, 嫚 represents disdain or insult.
