During Tyga and 21 Savage's flair up over Kylie Jenner, Savage used a line from Drake's Meek diss 'Back To Back' to go after Tyga.

When Drake (or whoever) wrote the line, he was referring to Nicki Minaj as the "boss bitch" who had "wifed" Meek Mill.

Which is why it was interesting that Meek responded to Savage's post, and that Nicki chimed in too.

What you doing #NickiMinaj

21 Savage has a close relationship with Meek Mill -- he  was spotted riding on the back of Meek's four wheeler in October.

Drake outdid Meek a couple weeks later by giving Savage a Ferrari for his birthday.

Now the rivals are both tangentially involved in Savage's beef with Tyga.
