A DM, aka a direct message, is a private, one-on-one communication feature on social media platforms such as Instagram, Twitter, and Facebook. Unlike public comments or posts, DMs allow users to send messages, images, videos, or links directly to another user or group of users, creating a private conversation.
DMs are often used for personal chats, collaborations, or customer service interactions. The term "sliding into the DMs" has also become a popular phrase, referring to the act of initiating a private conversation, often for networking or romantic purposes.
