He said they motivated him
And normally that would be ammo to hate on him
But that ain't my M.O! My M.O. is to be mo' motivatin'
This new-wave culture is so cultivatin'!
Where the fuck do I fit in?

That was enough reason for him to go at Ye on a diss track, but he doesn’t operate like that. (M.O=Modus Operandi ).
This new culture has a lot of hypocrisy and dissing involved.. He doesn’t fit in.
