The expression "pipe down" is a way of telling someone to be quiet or stop talking. You might use it in a situation where someone is talking too much or loudly and it's becoming annoying or disruptive. For example, if you're in a movie theater and someone is talking loudly during the film, you might say "Can you please pipe down?" as a way of asking them to be quiet. It can also be used in a more general sense to tell someone to stop complaining or being negative.
