The shoulder shrug is also a good example of a universal gesture that is used to show that a person does not know or understand what you are talking about. It is a multiple gesture that has three main parts: exposed palms, hunched shoulders and raised brow.
The Ring or ‘OK’ Gesture
The ’OK’ meaning is common to all English-speaking countries and it means "All correct".
The Thumb-Up Gesture
In Britain, Australia and New Zealand the thumb-up gesture has three meanings, it is commonly used by hitch-hikers who are thumbing a lift, it is an OK signal, and when the thumb is jerked sharply upwards it becomes an insult signal, meaning ‘up yours’ or ‘sit on this’. In some countries, such as Greece, its main meaning is ‘get stuffed’.
Congruence (state of agreement)
We often see a high ranking politician standing behind a lectern with his arms tightly folded across his chest (defensive) and chin down (critical or hostile), while telling his audience how receptive and open he is to the ideas of young people.
