sycophant

A sycophant is a person who acts obsequiously toward someone important in order to gain advantage. The mental image is of someone hovering closely, offering insincere flattery or excessive praise to a superior, essentially "fawning" to climb the social or professional ladder. The term carries a strong negative connotation, implying a lack of integrity and a cowardly focus on self-interest. It is often used in political or corporate environments to describe "yes-men" who agree with everything a boss says, regardless of whether it is right or wrong.
