The term Mita refers to the act of being great or doing something great. It is often linked with Mitaism- a religion devoted purely for people who admire Mitas. Mita can also be used to illustrate intelligence and beauty. The opposite of Mita would be Stephanie.
Oh My Gosh, she is so hot!! she's such a Mita!
