Actually, it is originally from a Def Leppard song called Rock of Ages. "GUNTER, GLIEBEN, GLAUTEN, GLOBEN" is what the band sort unofficially calls it, and it means absolutely nothing. It's just something that producer Mutt Lange used to make the recording sessions a little easier instead of saying one, two, three, four.
