Waving your hand in the air in a circle means one is coming right back.
Also, if a woman hit the floor with her hand (palm) strongly it means a threat and is marking her territory (slums). Someone that move his/her mouth like pointing, that is exactly what she/he is doing: Pointing. If someone wave their hands at the twist level while move the head and take a threatening pose; it is a really threat (slums). To touch or to pat the elbow means that is telling someone else is stingy.
