Drake appears to call out Kid Cudi with the lyric "You were 'The Man on the Moon,' now you just go through your phases. Life of the angry and famous." (Cudi's first two albums were Man on the Moon: The End of Day
and Man on the Moon II: The Legend of Mr. Rager
). Also, the titular "stone" may also be short for "stoner" as Cudi is well known for his druggy persona.
The mocking of the Day 'n' Nite
rapper caused controversy on social media as many saw this as a slight to his depression and suicidal instincts. Cudi had checked into rehab just a couple of weeks before Drake dropped this song.
