Buzzkill

A buzzkill is a person or thing that diminishes excitement, enjoyment, or enthusiasm in a social setting. This term is often used in informal contexts to describe someone who disrupts a fun or lively atmosphere, usually by expressing negativity, pessimism, or an overly serious attitude. Buzzkills can detract from the joy of an experience, making others feel less inclined to partake in activities or conversations that are typically lighthearted or celebratory.
