Dig through the ditches
Burn through the witches
Slam into the back of
my naked ass.

The story:

I have my new boyfriend in the car with me. I'm driving. This song comes on, and I start singing the lyrics really loud, banging my head and shaking my fist, really being silly about it. I come to the part where I'm slamming into the back of his "naked ass," and my new beau just freezes. A look of sheer terror crosses his face. He turns off the radio and asks me what I mean by that.
