What he did or didn't do isn't really what's important important here. What however, is critically important:
1) It is NEVER ok to verbally torture to blackmail someone for something they've done in the past
2) Things are not clear-cut like they often seem
Young Thug said "Right pocket relish, left pocket lettuce"
That's:
Alliteration - RpR, LpL
Metaphor - food to money
Imagery - green cause money
Rhyme - relish, lettuce
And your favorite rapper? Raps about being biracial so he can get an n word pass smh
