Hand rubbing
Hand rubbing is a gesture that conveys in many cultures either that one has a feeling of excited expectation, or that one is simply cold. In Ekman and Friesen's 1969 classification system for gestures, hand-rubbing as an indication of coldness is an emblem intentional gesture that could equally well be verbalized.
Cultural differences
The gesture is widespread around the globe, although it is possibly more common in cultures of countries with colder climates than those with hotter climates. In South America, the gesture is used to imply that two women are lesbians.
Hand rubbing involves rubbing the palms of one's hands together. As a gesture of expectation, the rate at which one rubs the palms together is significant. A fast pace indicates expectation of something good for onesself. But a slow pace indicates expectation of something bad for someone else. Context also affects the meaning of the gesture. In context, the meaning can vary from an indicator of internal (anticipatory) tension to meaning "Oh good!".
