Is that a response to Drake, Meek Mill?

Seems like Meek Mill is trying to insinuate that he's too busy to respond to Drake. He took to Instagram now to share the picabove an wrote, "Right now I'm on the road still cashing out ..... Ima b in the studio soon.... 5hr ride to Montreal ...". Erm, is that your tour or your girl's tour? Meek is currently opening for Nicki Minaj for her tour
