The expression "pour/throw cold water on something" means to discourage or diminish someone's enthusiasm or excitement about something. It's often used when someone is excited about an idea or plan, but others are not supportive and try to find flaws or problems with it, causing the person to lose interest. For example, if you excitedly share your plan to travel abroad, but someone responds with negative comments about the cost, travel risks, or the countries you've chosen, they are pouring cold water on your idea.
