Donald Glover aka Childish Gambino aka Troy Barnes put out 18-track "mixtape" Royalty a few weeks ago, but he keeps releasing tracks that didn't make it. "Sour Face" was released on some kid named So Super Sam's free mixtape today and in it, Glover raps about being back when I was sweatin' 5 Gs / back when I was hookin up with Ali Brie -- stunt.
What does this MEAN? Is he trolling?
