The Offspring guitarist Noodles explained the song's meaning in a Lollipop Magazine
interview: "It's a song about this guy with a bad habit - he drives around shooting people on the freeway. That's sarcasm. It's a tongue-in-cheek look at, I dunno, psychosis. It's not the real thing."
The song was controversial for its lyrical content and themes, including the line, "stupid, dumb-s--t, Goddamn motherf--ker." Noodles recalled: "We got a lot of hate mail after Smash
was successful from parents with sticks up their asses. Evidently, some parents don't trust their children to have any intelligence of their own, or be able to tell the difference between sarcasm and an order barked at them."
The group tried explaining the song's meaning to its critics, but it made no difference. "Parents still had a problem with it. Like kids are going to hear it and suddenly think it's OK to go driving on the highway shooting people. Have some faith in your kids. If your kids don't know the difference, why don't they know the difference?"
