Getting guap, guess green is the new black
When something comes into fashion, people often say it is the new black, i.e. it can be worn with anything, will never properly go out of fashion etc etc.
Bank notes are green, Kweli is getting them because it’s fashionable. Note the internal (half-)rhyme between guap and black.
