Diznerty. Woop-wop. Weezy. Shake My Speezy.

Do you know what those words mean? The government's drug-jargon expert in United States v. Decoud, No. 04-50318 (9th Cir. Aug. 2, 2006), evidently heard them for the first time when he was listening to the surveillance tapes in that case. But that did not prevent him, according to the Ninth Circuit, from offering reliable testimony on their meaning, based on his "experience" and the "context." From the Decoud opinion:

For example, the expert gave a lengthy explanation of how he interpreted "diznerty" based on his understanding of a common speaking style in "most black communities" where they "will put an 'e' or 'ez' in words, such as, 'I'm at his housez,' something like that. Just as a certain slang, certain words. And here[,] 'diznerty' is just a slang on dirty."

But where's the ez? And where did that n come from?

After a little research, we can inform any aspiring crimefighters in our readership that sometimes your carefully cultivated ear for street vernacular is all you can go on. No definition of diznerty is offered, for example, at urbandictionary.com. There's nothing at that site on woop-wop either. On the other hand, no fewer than ten definitions are given for weezy. And apparently speezy can be either a noun, referring to a "place to congregate and enjoy life," or an adjective, "describing a pre-ejaculatory prone male." The noun use would presumably be intended in "shake my speezy," given the fifth meaning offered for shake.
