Came from super fat chick that ordered a dozen of dozen donuts. Meaning a really super fat chick that is likes donuts.

Playing the dozens is an African-American custom in which two competitors -- usually males -- go head to head in a competition of comedic trash talk. They take turns "cracking on," or insulting, one another, their adversary's mother or other family member until one of them has no comeback. In the U.S., the practice can be traced back to chattel slavery, when violence among slaves was a property crime with potentially draconian consequences. Verbal sparring became a substitute for physical contention. While the competition on its face is usually light-hearted, smiles sometimes mask real tensions.

The dozens can be a harmless game, or, if tempers flare, a prelude to physical violence. But in its purest form, the dozens is part of an African-American custom of verbal sparring, of "woofin'" (see wolf ticket) and "signifyin'," intended to defuse conflict amicably, descended from an oral tradition rooted in traditional West African cultures. The dozens is a contest of personal power -- of wit, self-control, verbal ability, mental agility and mental toughness. Defeat can be humiliating; but a skilled contender, win or lose, may gain respect.

"Yo' mama," a common, widely recognized argumentative rejoinder in African-Amercan vernacular speech, is a cryptic reference to the dozens.

The term "the dozens" refers to the devaluing on the auctionblock of slaves who were past their prime, who were aged or who, after years of back-breaking toil, no longer were capable of hard labor. These enslaved human beings often were sold by the dozen.
