Bowing (also called stooping) is the act of lowering the torso and head as a social gesture in direction to another person or symbol. It is most prominent in Asian cultures but it is also typical of nobility and in many countries and distinctively in Europe. It is also used in religious contexts, as a form of worship or veneration. Sometimes the gesture may be limited to lowering the head such as in Indonesia, and in many cultures several degrees of the lowness of the bow are distinguished and regarded as appropriate for different circumstances. It is especially prominent in India, Thailand, Laos, China, Korea, Taiwan, Japan, and Vietnam where it may be executed standing or kneeling. Some bows are performed equally by two or more people while others are unequal - the person bowed to either does not bow in return or performs a less low bow in response. A nod of the head may be regarded as the minimal form of bow; forms of kneeling, genuflection, or prostration which involves the hands or whole body touching the ground, are the next levels of gesture.
In European cultures — aside from bows done by performers on stage such as at the curtain call — bowing is traditionally an exclusively male practice, and females instead perform a related gesture called a "curtsey" or "curtsy." The depth of the bow was related to the difference in rank or degree of respect or gratitude. In Early Modern European courtly circles, males were expected to "bow and scrape" (hence the term "bowing and scraping" for what appears to be excessive ceremony). "Scraping" refers to the drawing back of the right leg as one bows, such that the right foot scrapes the floor or earth. Typically, while executing such a bow, the man's right hand is pressed horizontally across the abdomen while the left is held out from the body. Social bowing is all but extinct, except in some very formal settings, though hand-kissing of women by men, which of necessity includes a bow, lingers on in some cultures.
