私信, PM
a private message sent on a social media platform, online forum, etc.
A PM, which is short for private message, refers to a direct, private communication sent between users. Unlike public posts or comments, a private message is only visible to the sender and the recipient. PMs are used to have personal or confidential conversations, share content, or discuss topics without others seeing the interaction. Most social media platforms, like Facebook, Instagram, and Twitter, offer this feature to allow users to connect privately.
