Digest a group and sell the poop on eBay
from Danger Doom – El Chupa Nibre Lyrics on Rap Genius
Meaning
DOOM is so nice, he metaphorically eats other rappers. And if other rappers can make money selling shit, he can as well.
Also possibly another Futurama reference, as Nibbler’s poop is “dark matter” an incredibly dense expensive form of spaceship fuel.
