When it comes to describing something that is considered to be low-quality or of poor taste, there are several synonyms that can be used as an alternative to the word "trashiness". Some of these synonyms include tackiness, kitschiness, gaudiness, crassness, vulgarity, and tastelessness. Tackiness refers to something that is cheap and lacking in style, whereas kitschiness relates to something that is deemed to be in poor taste but still has an element of charm. Gaudiness is used to refer to something that is overly ornate and flashy, while crassness and vulgarity both describe something that is offensive and lacking in refinement. Tastelessness, on the other hand, refers to something that is without any discernible aesthetic sensibility.
