Halt dein Maul=Shut up/your mouth (it means pretty much the same as "Halt Die Fresse")
one classic by Sido. raps about various people who tryna tell him what life really is about.. but Sido just responds that they don't know shit, so "shu-, shu-, shu-, shut your mouth"... these smart asses, here "his teacher, doctor, drug dealer, Angela Merkel etc.".
enjoy, oldschool German Rap fans!
