I'm in the trenches, relax

Lil Durk's verse in Drake's hit single "Laugh Now Cry Later". A popular phrase used by some. It means, despite gaining a lot of fame and wealth, Durk is still in the hood. Lil Durk has not forgotten where he came from.

Malachi: The boy, Jacob, catted. The boy think he all that, now he don't wanna be associated with us.
Jacob: I'm in the trenches, relax.
