Well this is surprising ... "Jersey Shore" star Pauly D actually supports a New Jersey town's war on saggy pants -- telling TMZ, "I'm not trying to look at guys' asses going down the street."
As we reported, several big rappers -- including The Game -- have spoken out against the City of Wildwood's recent ban on saggy pants along its boardwalks, claiming it's a racist law that targets black people.
But Pauly D doesn't think so ... saying, "Put a belt on!"
Oh yeah, we also talk about air sex. It's a thing.
