The term "mojo" is a slang for 'charm' (it is also used to describe 'séx appeal' or séx drive'; illegal drugs).
We think that when Kid Cudi says "his mojos so dope" it means "his magic or charm is cool or awesome."
During a pre-release playback of some of Mr. Rager's tracks to music journalists and insiders, Cudi explained this cut ("Mojo So Dope") is a message to the bloggers who are dissing him.
