spoilsport

A spoilsport is a person who, by their behavior, spoils the enjoyment of others. This term is often used informally to describe someone who dampens enthusiasm or ruins a good time, particularly in recreational or social settings. The actions of a spoilsport can range from complaining or being excessively negative to deliberately undermining a game, activity, or event.

The motivation behind a spoilsport's behavior can vary. Sometimes it stems from insecurity, envy, or a desire for attention. In other instances, a person might genuinely feel that the activity is unsafe, unfair, or inappropriate, and express their concerns in a way that is perceived as spoiling the fun. It can also be a passive-aggressive behavior to express displeasure or exert control.

Identifying someone as a spoilsport is subjective and depends on the context and the perspectives of those involved. What one person considers spoiling the fun, another might see as a valid point or a difference in opinion. The impact of a spoilsport can lead to frustration, resentment, and a negative atmosphere for the group. Dealing with a spoilsport often involves communication, setting boundaries, or, in some cases, simply ignoring their negativity to preserve the enjoyment of the majority.
