A gesture is a form of nonverbal communication. A gesture that may be insignificant or positive in some countries may be quite offensive elsewhere.
- A-ok or Okay — made by connecting the thumb and forefinger in a circle and holding the other fingers straight or relaxed in the air, may signal the word okay. While the gesture is positive in some countries, in certain parts of middle and southern Europe (although not in Spain or Portugal), Turkey, Latin America and Arab world, the gesture is considered offensive and disgusting.
- Fig sign – made by forming a fist and putting the thumb in between the index and middle fingers, used for the "got your nose" children's game in some countries. In areas including Turkey and some Slavic countries it is offensive.
- Mountza — In Pakistan, showing the palm of the hand to someone is considered an insult and very offensive (if the hand is in close proximity to their face).
- Hand-kissing — While this gesture indicates courtesy, politeness, respect or admiration in certain cultures, it is frowned upon in Muslim world, where this gesture is considered disgusting.
- Pointing — Pointing with an extended index finger may be used to indicate an item or person but pointing at another person is considered rude in many cultures.
- Waving — In many parts of the world, waving is a friendly gesture, indicating "hello." However, in Malaysia, at least among the Malays in rural areas, it means "come over," similar to the index finger bent toward the body, a gesture which is used in certain Western countries, and should be used only for that purpose.
