Childhood Shame Game

I was reminded by a coworker of the gestere where one points their left index finger toward a person, rubs their right index finger along it (as though whittling wood) and says a little rhyme. In my schoolyard the rhyme was always:

"Shame, shame, double shame,
Now we know your boyfriend's** name"

Now I see that other people had variations on the rhyme, as seen here: What gesture do you use to indicate 'Shame on you!'? Of course this article also brings up other "shame" gestures, such as the wagged finger which often accompanies that "tsk tsk" noise.

Anyway, we were trying to decide what that wood-whittling gesture was supposed to indicate. Is it phallic? Is there a sign-language equivalent? For that matter, how do hand signs/gestures evolve as language? Dammit! I'm going to have to do research now.



(**girlfriend's, if we were pointing at a boy; same sex was not an option, unless we were feeling particularly nasty.)
