Body language and gestures are a form of non-verbal communication that uses physical movements and expressions to convey messages. Some common gestures include waving or nodding with the head, clapping or shaking hands with the body, and winking or sticking out the tongue with the face. Gestures can vary between cultures, for example Spanish culture uses pinky promises and only handshakes for greetings, while English culture also employs air quotes and loser signs.
