deadass

/ˈdɛdæs/ Beginner Updated

Deadass means “seriously” or “for real.” It’s used to stress that you’re not joking, or, as a question, to ask whether someone else is.

What does deadass mean?

Deadass works like fr or no cap. Placed before or after a statement, it means you completely mean it: “I’m deadass leaving if he shows up.” Sent alone as a question, “deadass?” means “are you serious?”

It contains a mild swear word, so it’s casual and best avoided in formal settings.

How to use deadass

  • “Deadass, that was the best burger I’ve ever had.”
  • A: “I quit my job today.” B: “Deadass?”
  • “I’m being deadass right now, stop laughing.”

Deadass vs. fr vs. no cap

All three insist on honesty. Fr is the most neutral and widely used. No cap focuses on not lying. Deadass is a little stronger and carries a New York flavour.
