One might say "I have recently purchased a Cadillac and I was wondering if I could have some d's put on it?" or, in more ghetto terms, "Just bought a cadillac, throw some d's on that bitch." Another way in which the term d's can be used is, "D my car bitch." or "Could you please d up my vehicle" Image:WWTS1sted1.png "D's"is a part of Wikiality.com's dictionary, "Watch What You Say".
