In old blues songs, dating to at least 1909, "daddy" is slang for pimp. According to the Random House Historical Dictionary of American Slang, the oldest usage dates to 1681, when the speakers were hookers who used the phrase in reference to their pimps or to an older male customer. The origins of the full phrase are obscure, but the slang use of "daddy" has long been associated with prostitution. While the phrase has its innocent overtones - in the 1969 Zombies hit "Time of the Season," the singer investigates a potential love interest by inquiring, "What's your name, who's your daddy?" - its most direct and historic meaning has been sexual.

In other words, "Who's your daddy?" has gone mainstream.

It was the chant by New York Yankees fans during the 2004 baseball playoffs, and the name of a new-low-in-reality-television "special" on the Fox network last night (adult female contestant, adopted as an infant, tries to guess which man is her biological father). It has been the title of a 2003 straight-to-video movie (starring Ali Landry, heretofore semi-famous as the Doritos spokesmodel), and of a popular song and video by the country singer Toby Keith in 2002. This question keeps popping up like an insistent prairie dog. Instead, it's a demand, a boast, an all-around statement of superiority in three simple, yet quizzical words: It's not really a question, even with that punctuation mark appended to the end.
