This song finds Kesha at her most sexual and irreverent. The down and dirty Southern tune initially started out as an ode to the singer's beloved car before becoming an homage to her genitals. She said: "It began as a song about my car, which is a gold Trans Am, and it works about 40 per cent of the time. I don't have another car because I love that one so much. But then like all great pop it became a metaphor for something else - my p---y." (Source The Sun)
Kesha co-wrote the song with her mom, Tennessee songwriter Pebe Sebert. She told Q magazine that no subject is off limits during their mother-daughter collaborations: "We write songs about boys and sex together." she said. "That may not be normal to the average psychiatrist out there but I think it's pretty cool ... Don't analyze. That's the problem with so much culture out there. People are so trapped into trying to do the right thing. As long as you are not hurting anyone I think you should feel free to indulge your fantasies."
