Spitting up blood, shark by sharp precision
from Childish Gambino (Ft. Hypnotic Brass Ensemble & RZA) – American Royalty Lyrics on Rap Genius
Meaning
RZA is explaining how he is systematically destroying folks and leaving them hocking and coughing up blood (assumed from being verbally “beaten”). Blood can excite a shark’s appetite hence, he is a shark to the blood of these weaker people (or MC’s) and feeds off of their demise.
