What does it mean when a man while sitting or standing and talking to a man puts his hands behind his head and stretches his shoulders back so that his chest puffs out while maintaining eye contact?

When a man sits or stands with his hands behind his head and his chest puffed out while maintaining eye contact, it often signifies confidence and dominance. This body language can indicate a relaxed yet assertive posture, suggesting that he feels secure in the conversation and may be trying to assert his authority or presence. Additionally, maintaining eye contact during this posture reinforces engagement and interest in the interaction.
