Dt

In internet slang, “Dt” stands for “Don’t tell.” It is used to express the desire for something to be kept a secret or to prevent someone from revealing certain information to others.

Examples:

1. Person A: Hey, guess what? I heard a rumor about our boss!
Person B: Dt! We shouldn’t spread rumors about others.

2. Friend A: I need to talk to you about something confidential. Can you promise not to tell anyone?
Friend B: Absolutely, Dt! Your secret is safe with me.
