Never heard "Backpfeifengesicht". "Backpfeife" is an older word for "slap in the face". "Gesicht" can be directly translated to "face". Backpfeifengesicht is like saying "got a slap in the face in my face". Weird.
Oh, wait. Seems to be a 1999 song from "Die Γrzte" (the doctors), a German pop-punk band.
What comes way closer to the "d*ckhead'" mentioned in the video is "Arschgesicht" - literally "B*tthead".
