Like Hitler, it's the New Orleans Nightmare
Lil Wayne is the “New Orleans Nightmare” meaning the “baddest” (but bad means good like how kids say it) motherfucker in New Orleans
Hitler would also be a Nightmare for New Orleans since New Orleans is full of minorities who Hitler would want to have killed (this Hitler reference did not come out of nowhere — when he says “not see” in the previous line, it sounds like “Nazi”)
This is also a reference to the Nazi takeover of the French city of Orleans in World War II.
