Dope = good, awesome shit = stuff/thing “Ass” in this sentence intensifies the phrase. It doesn’t mean “butt” in this sentence. If we put all these together: “Some REALLY good stuff” Although, the sentence you posted doesn’t really make sense (or atleast I can’t understand it well). Also, please don’t use the word in formal sentences, because for one: they’re swear words, and two: they’re very informal (only use them with your close friends). :)
