The act of scratching someone’s palm, especially between a man and a woman, can have different meanings depending on cultural and personal contexts. In some cultures or social groups, it is seen as a subtle romantic or sexual gesture, used to express attraction or interest.
However, this interpretation is not universal. In many regions, the gesture may have no special meaning at all and could simply be a neutral action. Its significance largely depends on the setting and the individuals involved. If it occurs casually or in a spontaneous interaction, it may not carry any particular message.
