The term "tacky" refers to something that is considered tasteless or lacking in style. It often describes items, decorations, or behaviors that are overly flashy, cheap, or gaudy. For example, a brightly colored plastic lawn ornament might be seen as tacky because it does not fit well with the surrounding environment or lacks sophistication. In fashion, a tacky outfit might include clashing colors or excessive embellishments that draw attention for the wrong reasons. People often use the word to express disapproval of choices that seem to prioritize shock value over elegance, such as certain trends in pop culture or celebrity fashion.
