gaud
Tasteless bright ornament
A gaud is a showy ornament or trinket, typically cheap or tasteless.
The word carries a whiff of disapproval—gauds are flashy without being fine, decorative without being beautiful: The Christmas tree was loaded with gauds and tinsel.
The related adjective gaudy is more common.
