Green Flag Meaning: The Dating Slang and How to Use It

A green flag is a good sign — the positive opposite of a red flag. Here's what green flags mean in dating and how to spot them.

Green Flag Meaning: Quick Answer

Definition and Origin

A green flag is a positive sign — a good quality or healthy behavior that suggests someone (or something) is worth your time. It's the direct opposite of a red flag, and it's most common when talking about dating.

The phrase comes from the world of signals: a green flag on a race track or at sea means “all clear, go ahead.” Dating culture adopted it in the 2010s as social media popularized “red flag” warnings — and green flag became the reassuring counterpoint.
