Chicago producer Young Chop has been especially hard on Atlanta and its artists during his meltdown, even taking a field trip to the city to call out rappers like 21 Savage.

So it stands to reason 21 Savage's recent comments that drill music, the genre Chop and Chicago are associated with, actually originated in Atlanta are a shot against Chop.

As Savage explained in an IG Livestream, Atlanta rapper Waka Flocka Flame is the father of drill.

"We been on that sh*t done here. Waka Flocka really started that sound. Facts," Savage said.

If Waka Flocka is drill's daddy that would put its date of birth around 2008.  And, yes, 21 Savage had left jolly old England for the U.S. by then.

Is Savage speaking facts?
