trumperily
This adverb describes a manner of behavior or appearance that is ostentatiously showy but lacks genuine value or substance. It carries a strong pejorative tone, suggesting a desperate attempt to impress others through superficial glitter or fake prestige.
Because it is an archaic or rare term, using it in modern conversation may come across as intentionally quaint or overly literary. It is most effective when describing the gaudy pretensions of a character in a historical or satirical context, contrasting the outward flash with an inner emptiness.

Etymology
Derived from the adjective "trumpery," which comes from the Middle English "trumperie," meaning deceptive finery or knick-knacks. The root is linked to the Old French "tromper," meaning to deceive, which shares an origin with the Latin "rumpere" (to break), evolving through the sense of breaking a promise or tricking someone.
