I know when I was a collegiate my chapter could not stand snapping. We didn't care who you were. If you snapped you'd get looked at like you were a three headed monster! It was just toooo "sorority girl" and my chapter was the anti-sorority sorority. I don't know how my chapter looks upon it now since the dynamics have changed a lot. But I still cringe when I hear snapping.

SPARKLES. Also known as spirit fingers.

I loved that!
