What is Oniomania more commonly known as?

Oniomania is more commonly known as compulsive shopping. This term describes a psychological condition where an individual feels an uncontrollable urge to shop, which can lead to significant financial issues and emotional distress. The defining characteristic of oniomania is the compulsive nature of the shopping behavior, which often goes beyond simply enjoying buying items to a point where it becomes a means of coping with emotional or psychological issues. This aligns closely with the broader understanding of compulsive behaviors.

While the other options describe related concepts, they are not as precise as "compulsive shopping." Compulsive spendthrift and excessive buying may suggest a broader range of spending behaviors, while impulsive spending focuses on spontaneous purchasing without planning, which doesn't capture the compulsive and often distressing nature of oniomania.
