A parody of the sex crazed rock bands (particularly of the hair metal genre) of the 1980s.

“Hiro, our bass player at the time, hated that song. He thought it was obnoxious butt rock, a total rock'n'roll cliche. We tried to explain to him that the song was making fun of butt rock. We were fed up with bands beating about the bush, just using euphemisms and metaphors for the sex act. We thought we’ll ditch all the euphemisms and say what all the disco dance bands had been trying to say for a decade. We were simply trying to kick all the lame-ass rock'n'roll and dance music of the ‘80s and late '70s in the butt. It’s a parody of the whole genre of stupid rock.”
