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."
