Definition
A 'wet blanket' is someone who discourages enthusiasm or enjoyment; similar to a spoilsport or killjoy, but often unintentionally. They tend to dampen the mood with their pessimism or lack of excitement. It's as if they are literally throwing a wet blanket over a fire, extinguishing the flames of enthusiasm. They don't necessarily mean to ruin the fun, but their presence has that effect. 😔
