Addis means New in the Ethiopian language Amharic. It is a common name for both males and females.

Addis the girl is fun, crazy, spontaneous, very good looking, love tattoo's, bad boys with tattoo's or just plain old bad boys in general. Wears her heart on her sleeve and will do anything for the people she loves. If she hates you she'll probably punch you in the face! but she has way more love than hate. This girl rocks your socks off!!
Guy 1: Damn that Addis chick punched me in the face!
Guy 2: Wow you must really be an asshole
