Four Star Phony

Four star phony: Often used in the military to describe an officer who has never seen any real combat. A person of superior position in a company, culture, or society that has not earned his position through real experience. A person who has not “been there done that” but claims to have. An expert at conveying false impressions about ones importance. The liar that is highest up the food chain.

Our manager Mr. Smith sure likes to bark orders, but he doesn't know the first thing about running this department.
He is such a four star phony.

That four star phony sure likes to tell some fantastic stories about the old days.
