I'm such a damn Dickens
Tip is doing a common mid nineties rap trope where instead of calling himself something explicit he flips it. You think he might be saying he is a dick, but he adds the “ens” at the end.
This is a reference to Charles Dickens, a prolific fiction writer and author of A Tale of Two Cities, not a poet, who certainly knew how to make the plot thickens. Tip is following up on his earlier reference about dabbling in books; he gets the pickens (as in the choice ideas from books, in this case, books by Charles Dickens)
