The 'sucking their teeth' biz - is that what's normally written as 'Tut-tut'? That used to be a common expression of disapproval in Ireland, and I think I've seen it in old English and French films too. I used to work with an executive who commonly tutted in disapproval of his inferiors' work, and they had nicknamed him Skippy (after Skippy the Bush Kangaroo, who made the same sound).

The finger-and-thumb-in-circle gesture is one to be wary of. In some cultures it means 'perfect', in others 'ok', and in others it is an offensive gesture, the female equivalent of the extended middle finger (which itself only entered the non-American lexicon in the 1970s or so, I think).

Other gestures have gone out of use, like a slow shaking of imaginary water off the fingertips, which in the 1950s-60s could mean, depending on context, 'what a drip' or 'way cool, man!' And the 'yack-yack-yack' gesture for someone who talks too much, of repeatedly opening and closing the hand so thumb and fingertips touch (with an accompanying closed-eyes look of pained patience)…

People in the west of Ireland used to point with lip or chin when I was little, and I still have the habit of doing that. Pointing with the hand was considered rude.
