And that dead body gon' smell foul when it fouls out

from Black Hippy (Ft. Ab-Soul, Jay Rock, Kendrick Lamar & ScHoolboy Q) – U.O.E.N.O. Lyrics on Rap Genius

Meaning

Wordplay on “foul” — foul smell of a rotting dead body and fouling out in basketball (or here, in the rap game).

If you foul out you get taken out of the game, and being killed takes one out the game…of life.
