... and every time you get in your car, you're going to hear my f--king song on the f--king radio, you piece of s--t. That's right. And then I'm gonna take all my clothes off, I'm gonna sit on a big, giant d--k-sometimes two-I'm gonna swing around, and then I'm gonna hold the record for the most-watched music video on Vevo. So then-you know, you can tell a lot about a person-I think you can tell how big their d--k is by how much confidence they have usually, and if I was a dude I'd probably have a really big d--k, 'cause I feel really good about myself now. So I'm gonna tell those motherf--kers that broke my heart, particularly one, to suck my fat d--k and to enjoy hearing this song for the rest of your life. This song is called Wrecking Ball."
