What in the world (no pun intended) is going on!? First, B.o.B went on a Twitter tirade about how and why he is a firm believer that the earth is flat, which he followed up with a Neil DeGrasse Tyson (and NASA) diss track “Flatline”. Well, just like on Twitter, the astrophysicist wasn’t having this, so he teamed up with his nephew to return the favor, dissing Bobby Ray back. But not only that… he does it over Drake’s Meek Mill diss track “Back To Back” which is fucking epic. Well played sir, well played.
