glib
fluent but insincere / superficial / smooth-talking
Adjective
This term describes a specific type of fluency that is perceived as deceptive or superficial. It suggests a speaker who can produce a smooth, polished response instantly, but whose words lack depth, sincerity, or honest reflection. It is almost always used with a negative connotation to imply that the speaker is manipulating the listener or avoiding the true complexity of an issue. In professional or political contexts, it characterizes a persona that prioritizes style over substance. While a person might be praised for being articulate, being called glib implies that their eloquence is a mask for insincerity or a lack of genuine conviction.
