“Who is this Bango Skank?”
   — Mia to Susannah Dean

Bango Skank is the name of a graffiti artist whose graffiti appears in many significant places in The Dark Tower Series. He first appeared in one of Peter Straub's short stories, The Buffalo Hunter.

His graffiti is seen in Topeka, on the fence surrounding the vacant lot, the bathroom stall in the New York Public library, the ladies room in the U.N. Plaza Hotel, and the tunnel leading from the Dixie Pig to Fedic.

He is never actually seen in any of the books, but it most likely that it is an alias for one of the Crimson King's followers, as the graffiti in the tunnel exclaims that "BANGO SKANK AWAITS THE KING!"
