A "wet blanket" is an informal term for a person who consistently dampens the enthusiasm, excitement, or enjoyment of others. This can happen by being overly negative, critical, pessimistic, or uninterested when others are trying to have fun or feel motivated. The expression comes from the image of a literal wet blanket smothering a fire, symbolizing how such a person can "smother" good moods or lively atmospheres. It is usually mildly negative and often used in social contexts among friends, family, or colleagues to describe someone who brings down the overall mood.
