spoilsport

Imagine you and your friends are building a fort out of blankets and pillows. Everyone is laughing and having a great time. Then someone comes along, knocks it down, or keeps complaining about the mess until the fun is gone. That person is a spoilsport. A spoilsport is someone who ruins other people's enjoyment, either on purpose or without meaning to. It does not have to be a big dramatic act. Even small things, like constant complaining during a game or a joke, can make someone seem like this. Sometimes they mean to ruin the mood, and sometimes they just do not understand why everyone else is enjoying it.

The word "spoilsport" describes someone who intentionally or unintentionally disrupts other people's enjoyment, often by stopping the fun, criticizing it at the wrong moment, or acting in a way that takes the pleasure out of a shared activity. The term is a compound of "spoil" and "sport," where "sport" historically refers to fun, pleasure, or pastime.

A spoilsport is not necessarily malicious; they might genuinely believe they are being realistic or helpful, but their actions still dampen the mood. For example, if everyone is excitedly planning a surprise party and someone blurts out the secret, that person is definitely a spoilsport. Or imagine a group playing a game: a spoilsport might keep arguing about the rules or complain so much about losing that the joy drains out of the competition.

While the word often shows disapproval, it is also frequently used playfully as a light rebuke among friends. You might say, "Don't be such a spoilsport!" to someone who keeps refusing a silly game, objects to every playful idea, or otherwise drags down the mood. In the end, a spoilsport is a person who takes the fun out of something for everyone else.
