Gai can be defined as attraction experienced by a non-binary that they consider to not be straight, but also not be same gender. Their attraction does NOT have to be considered a 'same/similar gender' to be considered not-straight - it is entirely down to the individual's own experiences and perceptions. A non-binary person may consider only some of their attractions to be not-straight, or all of them to be so, and they may identify as nblm, nblw, nblnb or any other orientation whilst also identifying their attraction as gai.
The term was intended to be similar in meaning to queer but specific to non-binary people & attraction. It essentially has a very similar meaning to diamoric, but is short and easy to use in a sentence and is less easily confused for nblnb.

Flag
The gai flag was designed by Tumblr user Orbisian-prinxess some time around December 24, 2017[1]. Orange is for solarians, yellow is for non-binary people in general, green is for stellarians, blue is for multi-attracted non-binary people who feel gai towards more than one gender, purple is for lunarians.
