Take one index finger, and point it at someone. Take the index finger from your other hand, and lay it across the first, at the first knuckle. Then repeatedly sweep the second index finger towards the other person. And you have to shake your head sadly and say, “Shame, shame.”
It’s a familiar gesture, but…where the hell does it come from? What does it mean, symbolically?
WAGs and whacked-out theories welcome.
