A red flag is a warning sign; a green flag is a good sign. There is no green-flag emoji with that meaning built in, so people use ✅ or 💚, or simply write 'green flag'.
What it doesn't mean
Dating is its best-known use, but Emojipedia also lists safety hazards such as dangerous beach conditions or severe weather, golf, and left-wing political symbolism.
In casual use, flags are often jokes about trivial habits ('he doesn't like dogs 🚩'). A real warning sign is about behaviour, not taste, and deserves words rather than an emoji.
What it really means
A red flag means "danger" in the physical world: on beaches, in warnings about the weather. 🚩 took that meaning into the group chat, where the danger is usually a person.
The character's official name is Triangular Flag on Post, and it came into Unicode 6.0 in 2010 with the Japanese phone emoji. Emojipedia lists a range of uses, from beach-safety signs and golf to left-wing politics, but its main life now is as a pictogram for the phrase "red flag": a warning sign, especially about someone you are dating.
The emoji works best in rows. One 🚩 is a raised eyebrow. 🚩🚩🚩 means get out now. Under a screenshot of a message, a stack of flags is a verdict delivered without a word.
It has also turned into a joke format. People flag harmless preferences, such as ketchup on pasta, not liking dogs, or replying to texts too fast, as 🚩, and everyone understands it isn't serious. That playful use sits beside the serious one, and the phrase has siblings: a green flag is a good sign, and a beige flag is something odd but harmless. We have pages on both.
The risk is that the two uses blur. Calling a real pattern, such as controlling or frightening behaviour, a "red flag 🚩" can make it sound as light as a pizza preference. When it's serious, say what is happening in plain words, and talk to someone you trust.
Where it comes from

In real life
- 'He said all his exes are crazy 🚩🚩🚩' — a row of flags for a serious warning sign.
- 'She puts ketchup on pasta 🚩' — the joking kind of red flag, about taste rather than character.
- 'Rip current warning today, the lifeguards have the 🚩 up' — the literal sense.
