"Tacky" refers to something that is considered tasteless or lacking in style, often due to being overly flashy or gaudy. This term is commonly used to describe clothing, decor, or behavior that does not adhere to social norms of good taste. For example, an outfit with clashing colors and excessive embellishments might be labeled as tacky. In social contexts, tacky behavior can include actions that are seen as inappropriate or lacking sophistication. This might involve making loud comments in a quiet setting or showing off wealth in a way that feels uncomfortable. Overall, tackiness is associated with a disregard for subtlety and refinement.
