A wet blanket
Meaning
A person who discourages enjoyment or enthusiasm among others.
Origin
Imagine a roaring campfire, bright and full of warmth, bringing joy to all around it. Now picture someone throwing a heavy, sodden blanket over those vibrant flames. Instantly, the crackle dies, the light fades, and only smoke and dampness remain. This vivid image of a fire being extinguished by a 'wet blanket' emerged in the early 19th century, particularly in American English. The phrase quickly caught on as a perfect metaphor for a person who, through their pessimism or disapproval, metaphorically douses the spirits and enthusiasm of a group, leaving everyone else feeling cold and dispirited.
Examples
- Don't invite Mark to the party; he's always such a wet blanket, complaining about everything.
- She was excited about the trip, but her brother’s constant negativity made him a real wet blanket.
