What is the proper term for the action :

When you shake your head and at the same time making a gecko-like sound using your tongue ?


Like when you see a kid doing naughty stuff, and you do this ~ ?

Buffoonery.

Tutting.

To tut
You tut
He tuts
she tuts
they tut
we tut

You mean 'tsk-tsking?'

While we're on the the subject of terminology, there should really be a term for that annoying thing where two people stumble left and right when they meet paths in a corridor. Makes people look and feel like idiots, everyone has done it at least once... I thought about that for a looong time while stoned last night.

There is, its German...

I can't remember it.

Tutting.

does it include head-shaking as well ?

or when shaking hands, when A is holding something in his right hand, so B decide to shake with left hand while A unloads his right hand, so they paused for a moment before mutually switching hands again.
