Don't mess with The Snap Diva. As you will learn through the video above, there are many ways to snap. Appears to be some experimental African-American gay theater/spoken word performance art (anyone know the source?). Out of context, it begs to be born anew as a meme. Found at Robert Popper's blog. I'm particularly fond of "The Medusa Snap."

Update: The clip is an excerpt from the 1991 PBS P.O.V. special "Tongues Untied," by Marlon Riggs. You can buy it on DVD here. Clip grabbed by and blogged recently at FourFour.
