Drake's diss of Kid Cudi in his new track 'Two Birds, On Stone' has  everybody yapping.

That's because Drizzy went after Cudi for being depressed at a time when the moody rapper/actor has checked himself into rehab for suicidal thoughts.

Drake pushed back against the criticism on IG.

Drake also had something more to say about Pusha T -- who he also came for in 'Two Birds, One Stone' -- during his comment creepin' session.

But back to Cudi:

Do you think he made himself permanent fair game when he mentioned Drake's name like he did?
