A person who uses their good looks, charm, and humour (if they posess it) to dominate others. He/she navigates the social or business world with the perception of having everything under control. Generally coming in at the lead, the top dog exerts a wide circle of influence around themselves.

Historically a male, recent times have seen the emergence of female top dogs as well.
