A triangular red flag on a silver or wooden post.

Commonly used to represent the term red flag, a warning sign, dealbreaker, or indicator of problematic behavior, particularly in dating and interpersonal relationships. Often seen as a string of multiple flags together (e.g. 🚩🚩🚩) to highlight toxic behaviors or personality traits.

Relatedly, it can also be used to signal general safety hazards, such as dangerous conditions at beaches or severe weather warnings. May be used to represent left-wing political ideologies.

Can also be associated with golf, as shown in the flag in hole emoji.

This emoji predates the inclusion of emojis within Unicode. It was first added to early Japanese emoji keyboards by Docomo in 1999/2000, though a 2003 design from au by KDDI more closely resembles the modern emoji.

Triangular Flag was approved as part of Unicode 6.0 in 2010 under the name "Triangular Flag on Post" and added to Emoji 1.0 in 2015.
