“OVO 40, hunched over like he 80, tick, tick, tick”
Here, Push goes for the jugular. Since Drake dissed Push’s producer, Kanye West, Push has put a target on Drake’s producer Noah “40” Shebib’s back. He continues, “How much time he got? That man is sick, sick, sick.” In 2005, Shebib was diagnosed with Multiple Sclerosis and has been an ambassador for the National Multiple Sclerosis Society for years, making Push’s dig here particularly callous. (It could be viewed as retaliation for Drake’s insults about Kid Cudi’s mental health.)

Chickens came home to roost.
