Mr. Solo Dolo
“Dolo” is an acronym for “done on lonely by oneself.” The word sounds like dolor, the Spanish verb for the experience of pain (or sorrow)
Kid Cudi feels like he is alone, but he also senses that the complaint is a little childish and mocks himself for it with the silly “solo dolo” rhyme
Cudi is trying to make a nickname for himself: he calls himself “Solo Dolo” in a bunch of songs on this mixtape, A Kid Named Cudi. .
Or Dolo could just be slang for getting high, and he does it by himself.
