Definition
A 'double-dealer' is someone who deceives or betrays others in their dealings, especially in business or politics. They present a false appearance of honesty while secretly pursuing their own self-serving agenda. Think of them as chameleons, adapting their behavior to manipulate others. Unlike a simple liar, a double-dealer engages in complex schemes and intrigues. This term implies a calculated and deliberate act of deception. It suggests a lack of moral principles and a willingness to exploit others. Beware of those who seem too good to be true!
