The vehicle of which the rapper Rich Boy claims to have just bought in the track "Throw Some D's". He claims that he would indeed like to heave some ten-thousand dollar "D's" (short for Dubs) at the car, resulting in damage to the vehicle, likely wasting much of the money that he claims to have.
However, my research shows that there is no such car named a "Caddalick."
Just bought a Caddalick. (Throw some D's on that bitch!)
