A person showing thumbs up can indicate approval or agreement. The thumbs-up gesture is achieved by a closed fist held with the thumb extended upward. In certain contexts, the use of the Thumbs Up emoji can be construed as being passive aggressive or sarcastic. A person displaying thumbs may also lean backward (apathy), tilt their head back, exposing the neck (dominance), or rock on the balls of their feet to increase their height (high status). ^{psychmechanics.com 1 2 3 4}
